Here is one workaround  I have

I don't know the fix to the problem (it has to do with TCP problems
on the SPARC end), but a work-around is to put the job into background
and then into foreground, e.g..

[unix] rlogin crufty-sun4 &
[unix] fg %1


However I got a copy of rlogin program from Berkeley BSD 4.3 distribution
and compiled it on the DEC3100 (running ULTRIX 4.1) and it works fine.
So one solution would be to get rlogin.c and compile it on your
DEC3100.
