I'm a little confused, if you're hooking up terminals to a terminal server
and then telneting to the Aix box it should behave exactly the same as SUN,
However, if you're trying to use the terminal server for some form of
console consolidation, i.e. doing reverse telnet connections, then I can
just about envisage your problem.
Aix is a little demanding in that it expects DCD to be lifted high when an
incoming connection is made, just the same as a modem really.
Unfortunately there is no standard way of implementing RS232 on RJ45
connectors. The important RJ45 information needs to come from your terminal
server vendor. IBM for instance uses two different standards between it's
own 64 & 128 port serial adapters and almost every terminal server I've
ever seen uses a different combination again.
What you need is the signal names on the RJ45 end and marry these up with
the DB25 RS232 standard.
I'd suggest you get some DB25 - RJ45 convertors. These have DB25 connector
( male or female) and a shell with an RJ45 connector in it. The wires with
the pins or sockets are left loose, you simply insert the correct colour
into the DB25 end.
You will also find things much easier if you have got access to a breakout
