I've heard of an interesting setup which might be a little cheaper than the Vadic VA4401P/VA1604 solution. Using standard Bell 202 2400 baud half-duplex synchronous modems, and Micom Micro-500 front ends, you end up with a 2400 baud async error-free interface. Total cost is about $1500. Cheaper than the Vadic solution, with the added bonus of error-free transmission (a real plus when used from home, let me tell you!). The only catch is that if both ends try to transmit at a full 2400 baud, flow control will be needed, because there is really only 2400 bits/second of throughput, not 4800 as required for a totally async 2400 baud connection. No problem for uucp or CPU<=>TTY communications. Most info courtesy of David Yost. You want to add anything, Dave? Rick Kiessig
