I'm not working on anything now - I just came up with the idea. I did some Googling, and there seems to be commercial units, all around $1K per end (async is much cheaper). Microcontrollers and digital electronics is another one of my hobbies. Async serial is simple for a microcontroller to handle. I've never actually looked to see if there's any synchronous libraries out there. Wrapping the data in UDP is simple. The HDLC layer could deal with error detection/correction. The problem is finding surplus time to embark on this. Maybe a few of us could collaborate on it?

We could use these to emulate leased lines on equipment that doesn't even have Ethernet boards. YES. Are you working with that sort of stuff? I ask because I am and could probably do it. -Dave -- Dave McGuire, AK4HZ New Kensington, PA Hello! That is a truly amazing idea. What sort of adapters are the both of you thinking of? ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again." --- Filter service subscribers can train this email as spam or not-spam here: http://my.email-as.net/spamham/cgi-bin/learn.pl?messageid=58228A76613511E2A…
