[linux-elitists] "reverse" rtty type of utility?

I'm throwing this request out this way since I've been unsuccessful in my web 
searches and the local communities have looked at me sideways for making such 
a request.  Perhaps the eclectic group here has some insight or experience in 

I'm looking for a "reverse" rtty/conserver/ttywatch type of program.

I have an Ascend Max which has 24 modems hanging off of a T1 that I'd like to 
present to HylaFax as character devices.  The Ascend has a "telnet-a-modem" 
feature whereby you connect to port 5000 and you are in a "live" session with 
a modem; you can send the standard fare of Hayes AT commands and so on.

Hylafax only works with character devices so I figured there might be 
something out there which emulated a regular character device and would relay 
the characters send to a telnet session, establishing it if necessary and 
relaying any characters sent by the remote side back.

The OpenH323 people have created T38modem which will emulate a character 
device (and faxmodem) and present the session to a T38-compliant voice 
server.  rtty and friends all do the opposite of what I'm looking for; they 
allow you to telnet to a local character device.

So, before embarking on my own mini Frankenstein's software monster I thought 
I'd ask and try and prevent some wheel-reinventing, if at all possible.
