In TCP/IP 1.2, some new options were implemented. It is possible that
the 1.2 telnetd or the NCSA code isn't handling them correctly. Other
telnet commands work with the 1.2 named but I have seen the problem with
AIX 1.1 on the PS/2 trying to connect to ISC.
The new options are flow control negotiation, terminal speed,
window size and X display location. For compatibility with telnet
clients that can't deal with these new options, they can be disabled
by adding a -X
