Clear as mud, huh?

What I would like is a piece of software that creates a virtual serial port
on the PC (say Com4) and opens a telnet session on the Unix box. I tell the
software that I want the port settings to be 19200,8,n,1. I tell the
terminal emulation program to use com4. Anything the serial port 'sees' gets
sent to the telnet session. Anything coming from the telnet session gets
sent to the serial port.

I found a few that looked hopeful, but didn't negotiate the telnet session
startup. I would like the login: prompt passed to the serial port. Pretty
much just a virtual terminal server.

The main issue is that we are finally upgrading. I have put in structured
cabling, but I'm still fighting fires with the various rats nests of wires
behind some of these PCs. The one I'm fighting with this this week has a
9-25 pin adapter on the serial port, with a DB25 M-M adapter, connected to a
DB25 to RJ11 adapter. Silver satin runs through the walls into a DB25 to
RJ11 adapter plugged into the DG Mux in the computer room.

I installed Putty on the misbehaving PC, and even configured the colors to
match the ugly ones the user had chosen, but now he's whining that he
doesn't have his print screen functionality.

It's going to be ugly when I put these folks on Windows based software. I
don't want to traumatize them twice.
