Purpose

Use the HELP (or ?) subcommand to access the help facility.

Parameters

There are no parameters for this subcommand.

Usage

• After your TELNET connection is established, your display station screen is controlled by the foreign host, so the help you see is different for line mode and transparent mode. The help available in transparent mode is abbreviated because TELNET does not have control of the screen.
• When you invoke the HELP or ? subcommand in line mode, TELNET displays the help information one line after another, as in the following example:

  Once connected, follow the log in and usage
  procedures of the remote host.
  To invoke one of several TELNET commands, hit a
  PF key (PF4-12, PF16-24), and then enter any of
  the following commands:
  Help or ? -- Receive (this) assistance
  AYT       -- Are You There?
  AO        -- Abort Output
  BRK       -- Break
  IP        -- Interrupt Process
  SYNCH     -- Clear data path, except for TELNET commands
  Quit      -- Quit the TELNET session
   
  The following PF settings are in force:
    PF1 or 13 -- Retrieve previous input line
    PF2 or 14 -- Scroll halfway up
    PF3 or 15 -- Turn off display of user-line; designed
                 to be used before entering password
  For control characters, enter ¢c or `c where c is:
   "0": 00, "a" - "z" or "A" - "Z": 0x01-0x1A
                         "2" - "6": 0x1B-0x1F
   "{": 0x5B, "}": 0x5D, "#": 0x7F

• When you invoke the HELP or ? subcommand in transparent mode, TELNET overwrites one line of the current screen with the help information, as in the following example:

   
    Valid TELNET cmds: AO,AYT,BRK,IP,PA1,QUIT,SYNCH.
