Reserving a TN3270 port using INTCLIEN does not work when TN3270 is running as its own
procedure. INTCLIEN implies that TN3270 is running within the TCP/IP stack’s address
space. If INTCLIEN is specified, the stack rejects the BIND request from TN3270 running as
its own standalone procedure.
Multilevel security compliance
Because the Telnet server does not get notified of RACF terminal class updates, TN3270
running as its own procedure is not multilevel security compliant. Releases of CS for z/OS
beyond V1R8 will provide a mechanism to notify the Telnet server of RACF terminal class
updates
