There were some fixes to terminal handling and such in 3.2.  I'm using
ksh88 right now, and log in to 3.2 systems all the time via rlogin and
telnet (from terminal servers).  I vaguely remember having a similar problem
when first porting ksh88, so I think it's the port, not telnet.

Check are that you use RAWONLY mode, I believe this may have something to
do with it.  Perusing the local port, the only sgi specific changes I made
were 1) fixed the infinite loop bug in history.c when opening a history
file, and 2) added some define's to jobs.c to make job control work.
Other than that, raw mode seems to be the interesting one.
