The Question is:
How do we increase the telnet session limit?
The Answer is :
Increasing the session limit is explicitly described in the
Configuring and Managing Telnet chapter of the TCP/IP Services
Management documentation, and the specific details vary by the
TCP/IP Services version.
Assuming TCP/IP Services V5.3 -- the current version, as of this
writing -- the cited chapter includes the TCPIP$TELNET_VTA logical
name used for configuring virtual terminal support, and details of
the SET SERVICE TELNET /LIMIT=n command used for increasing the
telnet session limits.

and various others. Numerous discussions of telnet printing and
of reverse telnet also exist here in Ask The Wizard.
