If the user needs the ability to choose an application, you can create custom solicitor screens using unformatted system services (USS) message tables. These tables are mapped to clients using the USSTCP mapping statement. For example, use the following statement to map a USS table, USSTAB1, to any TN3270 or TN3270E client identified by any link name that starts with LINK. When a TN3270 or TN3270E client connects, Telnet will immediately send a custom logon screen (USSMSG10) from the USS table.
LINKGROUP LNKGRP1 LINK* ENDLINKGROUP
USSTCP USSTAB1 LINKGRP1
Assembled USS tables used by VTAM® can also be used by Telnet.
