  I don't know if this product exists, but I'd like to know.  In particular,
I'd like to run 4 serial lines (300-1200 baud lines) into a black box, and
run a single line out of it to a high speed modem.  When I get to where I'm
going, I want to do the opposite.  

  ------300 baud line-----\                       /---300 baud line----
  ------1200 baud line-----\_X__telebit modem__X_/----1200 baud line---
  ------300 baud line------/                     \----300 baud line----
  ------1200 baud line----/                       \----1200 baud line--

What I'm asking about is "X" in the above picture.  I could probably work
something out with a PC and a multiport card and some software, but I'd rather
buy a product off the shelf.  

Purpose is to use the telebit modem (on 1 dialup line) and not have to pay for
4 dialup lines.  In other words, to save $.  I'd expect some slowdowns;
that's OK.  Anyone got any pointers on a product or products to accomplish
this?
