Parameter Description for RMT(nnnnn) (BSC)

DEVTYPE=type|2770

To specify the type of terminal or system at this remote location, specify one of the following:

Hardware Terminals	Multileaving Terminals	Systems
2770	2922	S/36
2780	M20-2	S/360
3781 (See note 1 below.)	M20-4	S/370
3781	M20-5	1130
	M20-6	S/3

If you are initializing a terminal that is not explicitly supported by JES2 (that is, one that is not listed above) but emulates one of the above listed terminals, consult the documentation for that terminal to be certain you set characteristics (such as buffer sizes) appropriately for that terminal.

Note:

To ensure that punch output is directed to the proper device, specify '3781' to define remote 3780 terminals that contain punches.
Specify a 3740 hardware terminal as a 2780.

Modification: $T RMT(nnnnn) operator command.

BLOCK=Yes|No

Specifies whether or not this terminal has a blocked (Yes) or unblocked (No) data record format.

Modification: $T RMT(nnnnn) operator command.

BUFEXPAN=0|1|2

Specifies whether or not this 2770 terminal has a buffer-expansion feature.

0: Indicates that this terminal does not have a buffer expansion feature.
1: Indicates that this terminal has the buffer expansion feature and implies a remote terminal buffer size of 264 bytes.
2: Indicates that this terminal has the additional buffer expansion feature and implies a remote terminal buffer size of 520 bytes.

Modification: $T RMT(nnnnn) operator command.

Note: If a printer attached to this remote has PRWIDTH= specified greater than 120, specify BUFEXPAN= 1 or 2.

BUFSIZE=nnnnn

Specifies the largest buffer (127-3960) that can be sent to or received from this BSC terminal. This parameter enforces minimum buffer size specification based on device type for BSC.

Following are the minimum values required to support various non-programmable terminals.

Minimum SIZE: Terminal Type
127: 2770, without any type of buffer expansion
264: 2770, with buffer expansion (BUFEXPAN=1 on RMT(nnnnn) statement)
520: 2770, with additional buffer expansion (BUFEXPAN=2 on RMT(nnnnn) statement)
400: 2780
520: 3780

Performance Considerations: This parameter can be used to reduce JES2 processor overhead when driving multileaving RJE workstations on high-speed lines. Proper specification can also increase throughput.

You can change this parameter value at the RJE workstation by: (1) regenerating the initial program load (IPL) data set or (2) specifying the multileaving buffer size before signon by placing an &MLBFSIZ initialization statement before the /*SIGNON statement. (See MVS™ Remote Workstation Generation, GC28=1433 for RJE statement descriptions.)

If you do not specify a value, JES2 provides the following defaults for the following device types:

Table 1. JES2 BUFSIZE Defaults for RJE Workstations
Workstation	Type	BUFSIZE Value
Multileaving Terminals and Systems	N/A	MBUFSIZE= value on TPDEF statement
Hardware Terminal	2770 without buffer expansion (BUFEXPAN=0)	127
Hardware Terminal	2770 with buffer expansion (BUFEXPAN=1)	264
Hardware Terminal	2770 with additional buffer expansion (BUFEXPAN=2)	520
Hardware Terminal	2780	400
Hardware Terminal	3780	520
Hardware Terminal	3781	520

Modification: $T RMT(nnnnn) operator command.

COMPRESS=Yes|No

Specifies whether (Yes) or not (No) this (2770 or 3780) terminal has the compression/expansion feature.

If you specified COMPRESS=No on the LINE(nnnnn) statement, for the line this terminal is to use, it overrides the value specified here. If you specified COMPRESS=Yes on the LINE(nnnnn) statement, whatever you specify here will take effect if COMP= is specified on the remote device (Rnnnnn.XXn initialization statement).

Note: COMPRESS=Yes and HTABS=Yes are mutually exclusive. If both are specified, HTABS=Yes will be changed to HTABS=No.

Modification: $T RMT(nnnnn) operator command.

CONDEST=nnnnn

Specifies the route code (1-32767) to be used for responses to commands entered from this RJE workstation. The value specified here should be equivalent to the nnnnn specification on a RMT(nnnnn) statement.

Note: This routing only affects nonspooled responses.

If you do not specify a value for this parameter, JES2 assigns the number of this terminal (RMT(nnnnn) ) as its route code.

Modification: $T RMT(nnnnn) operator command.

CONS=Yes|No

Specifies whether (Yes) or not (No) this multileaving terminal has an operator console or that it is simulating a console, as specified by the &PRTCONS RMT generation statement. See the MVS Remote Workstation Generation, GC28=1433 for an explanation of all RMT generation statements.

If JES2 determines that this remote can not have a console, JES2 forces the value of this parameter to NO.

Note: CONS=NO will not interrupt any streams for console messages. Console data will be sent when a session becomes available to the virtual console device. If CONS=NO is specified, data destined to a console can still be sent.

Modification: $T RMT(nnnnn) operator command.

Discintv=nnnnn|0

Specifies the interval (in seconds) after which, if there is no successful text transmission in either direction, this terminal will be disconnected from the processing unit. Error recovery tries and idle time are not counted as successful text transmission. The value of nnnnn may be from 0 to 8160 seconds; JES2 rounds this value to the next highest multiple of 32.

If you do not specify a value, this parameter defaults to 0, which indicates that this terminal is not to be disconnected.

Modification: $T RMT(nnnnn) operator command.

HTABS=Yes|No

Specifies whether (Yes) or not (No) this (2770 or 2780) terminal has the horizontal format-control feature.

Note: COMPRESS=Yes and HTABS=Yes are mutually exclusive. If both are specified, HTABS will be changed to HTABS=No.

Modification: $T RMT(nnnnn) operator command.

LINE=nnnnn|0

Specifies the number (0-65535) of the teleprocessing line that is connected to this terminal. Use a number (1-65535) to specify a dedicated line or 0 to specify a non-dedicated line.

If you specify no line number, JES2 assigns a default of LINE=0, which provides a nondedicated line. This line can then be used by multiple BSC RJE workstation with similar features when started with a /*SIGNON JCL statement.

Modification: $T RMT(nnnnn) operator command.

LOCAL190=INFO|ACTION

INFO specifies that operator setup messages ($HASP190) issued at the local (processor) console for this remote device are to be “information” messages, while ACTION specifies that the setup messages require operator action before they can be deleted from a display console.

Modification: $T RMT(nnnnn) operator command.

MFORM=J|M|T

Specifies the amount of information to be displayed in JES2 operator console messages for this RJE workstation.

J: Indicates that the message is displayed with the jobname and job ID of the issuer.
M: Indicates that only the message text is displayed.
T: Indicates that the message is displayed with a time stamp, jobname, and job ID of the issuer.

Modification: $T RMT(nnnnn) operator command.

MRF2780=Yes|No

Specifies whether (Yes) or not (No) this 2780 terminal has the multiple-record feature.

Modification: $T RMT(nnnnn) operator command.

MSGPRT=Yes|No

Specifies whether JES2 prints messages routed to a printer attached to the console of an RJE workstation.

MSGPRT=YES causes JES2 to print messages if the remote console is unavailable. MSGPRT=NO causes JES2 to discard messages if the RJE workstation console is unavailable.

Modification: $T RMT(nnnnn) operator command.

MULTILV=Yes|No

Specifies whether (Yes) or not (No) this terminal will use the BSC (binary synchronous communication) multileaving interfaces. If Yes is specified, the terminal type must specify a multileaving workstation. No defines this RJE workstation as an RJE BSC hardware terminal.

Modification: $T RMT(nnnnn) operator command.

NUMPRT=n|1

Specifies the number (0-7) of printers at this RJE workstation. Use the R(nnnnn).PR(m) initialization statement to specify the characteristics of each printer. JES2 can use values greater than 1 only if you coded MULTILV=Yes on this statement. A maximum total of 8 printers and punches may be specified.

Modification: $T RMT(nnnnn) operator command.

NUMPUN=n|0

Specifies the number (0-7) of card punches at this terminal. Use the R(nnnnn).PU(m) initialization statement to specify the characteristics of each card punch. JES2 can use values greater than 1 only when you coded MULTILV=Yes on this statement. A maximum total of 8 printers and punches may be specified.

Modification: $T RMT(nnnnn) operator command.

NUMRDR=n|1

Specifies the number (0-7) of card readers at this RJE workstation. Use the R(nnnnn).RD(m) initialization statement to specify the characteristics of each reader.

Modification: $T RMT(nnnnn) operator command.

Password=xxxxxxxx

Specifies a 1- to 8-character security password to prevent unauthorized users from using this RJE workstation's resources.

Modification: $T RMT(nnnnn) operator command.

RECFM=FIXED|VARIABLE

Specifies whether the data record for this terminal is fixed-length (FIXED) or variable-length (VARIABLE).

Modification: $T RMT(nnnnn) operator command.

RMT150=Yes|No

Yes specifies that if this RJE workstation has a console, the $HASP150 message is first sent to this console and then also sent to the local operator. No specifies that the $HASP150 message is sent only to the local operator.

Note:

If Yes is specified for this RJE workstation, and SYSTEM36 (S/36), CONS=Yes, and MULTILV=Yes are also specified, the remote printer will pause momentarily to ensure that the $HASP150 message arrives at the console before the data sets begin to print on the printer. There is no pause for systems other than SYSTEM36.
This parameter is not valid for hardware terminals.

Modification: $T RMT(nnnnn) operator command.

Routecde=nnnnn

Specifies the route code (1-32767) to be assigned to this terminal and its associated printers, punches, and readers. The value specified here should be equivalent to the nnnnn specification on a RMT(nnnnn) statement.

If you do not specify a route code, JES2 assigns the number of this terminal (RMT(nnnnn)) as its route code.

Modification: $T RMT(nnnnn) operator command.

SHARABLE=Yes|No|Default

Specifies whether (Yes) or not (No) JES2 allows the line specified on the LINE= parameter to be used by other RJE workstations.

Yes: Indicates that multiple RMT definitions can also specify and use the line specified on the LINE= parameter. A /*SIGNON JCL statement is required to start these RJE workstations.
No: Indicates that no other RJE workstations can specify and use the line specified on the LINE= parameter.
DEFAULT: Indicates that you want JES2 to determine the value of this parameter based on all RJE workstations definitions. JES2 sets this parameter to SHARABLE=No if a specific line number (LINE=nnnnn) is specified on only one RMT(nnnnn) statement. JES2 sets this parameter to SHARABLE=Yes if a specific line number (LINE=nnnnn) is specified on multiple RMT(nnnnn) statements.

Note:

If a RMT(nnnnn) statement specifies a LINE= parameter with SHARABLE=NO, but another RMT(nnnnn) statement specifies the same LINE= value, JES2 forces SHARABLE=Yes on all RMT definitions with the LINE= value at the installation when initialization completes.
If only one RMT(nnnnn) statement specifies a line and you do not specify the SHARABLE= parameter at initialization, you must use the $T command to set SHARABLE=Yes before you can use a $ADD RMT(nnnnn) or a $T RMT(nnnnn) command for another RMT definition that specifies the same LINE= value. Therefore, SHARABLE=Yes is recommended to avoid this situation, unless you want to specifically reserve a given line for use by a single RJE workstation.

Modification: $T RMT(nnnnn) operator command.

TRANSPAR=Yes|No

Specifies whether (Yes) or not (No) this terminal has the text-transparency feature. If you specify TRANSPAR=Yes, you must also specify TRANSPAR=Yes on the LINE(nnnnn) statement that defines the line for this RJE workstation.

Modification: $T RMT(nnnnn) operator command.

WAITIME=nn|1

Specifies the length of time in seconds (0-30) that RTAM should wait at the completion of the processing of any input stream, or printed or punched output stream, to allow the operator to enter an input stream at this RJE workstation.

Modification: $T RMT(nnnnn) operator command when the remote is inactive.
