aix and terminal servers

Wed Jun 19 12:03:38 AEST 1991

Once again this probably is a frequently asked question, but i have 
a rs6000/320 running aix v3.1.5/2006 and when one rlogin's from the 
terminal server no TERM variable is set so the tset is properly
performed, however if one telnet's in from the terminal server
then somehow TERM is set to ibm5091 (or something like that) and tset
is bypassed, which is annoying if one is using a vt100 or something
like that. Actually, this is probably a step in the right direction
since one couldn't telnet in at all from the terminal server with
3003.
This only happens with the terminal server, not when one tries to
enter from another host. Anyone know what is going on? Thanks.
