    I am using Interlisp-D(KOTO) on FUJI-XEROX 1121.  And I also have the
same problem.  The TCPFTP-Package works well with UNIX-Workstations such as
Sun-3, Sony-NEWS, and VAX11.  But TCPCHAT-Package can not connect to
SunOS4.0(Sun3), NEWSOS3.2(Sony-NEWS) and ULTRIX2.0(VAX), but can connect
to SunOS3.5(Sun-3), NEWSOS2.2(Sony-NEWS) and Bridge Communication-Server's
port.

    When I trace TCPCHAT's packet, it seems that the protocol of SunOS3.5
and SunOS4.0 are different.  (NEWSOS2.2 and NEWSOS3.2 has same problem.)
I think that NEW-UNIX(4.3BSD and like that) uses different TELNET-protocol
from OLD-UNIX(4.2BSD and like that) for some reason.  TCPCHAT knows only
one protocol of OLD-one, so TCPCHAT cannot connect to NEW-UNIXs.

I found difference of protocols, but cannot fix this problem.
