Is this SLIP
or PPP? 
 Neither.  It's a well thought-out (and documented!) protocol for interface
 between small 8-bit machines and modern hardware.  There's nothing
 specific to the CoCo - that just happens to be the first implementation. 
 
I just looked at it on sourceforge. It seems like the same setup of a
Lantronix UDS or Wiznet-type device. Those are a little more portable.
