[Coco] RS232 Pak needed

[Al Hartman]

There are no equivalent chips?

There's no way to implement a Serial Interface on a Coco without a 6551?

Why not then make a Parallel Interface? Laplink on the PC worked over 
bi-directional Parallel Ports.

Why not simply make a Parallel Port adapter, and then use a USB to Parallel 
adapter on the Server end, and re-write Drivewire to also use a Parallel 
port if available and chosen by the user?

A Dragon already has a Parallel Port, is it bi-directional?

6551's are getting pretty difficult to come by.  I did quite a bit of
testing of different 6551's for Roger a few years ago and had to scour the
Internet pretty hard just to find the ones I have.
