I kind of half asked this once before, but it was stuck in on another thread, so I think it was overlooked. Does anyone have info on how to use the I-Modem protocol for data transfers? (that's Eye-Modem). All I have been able to find is that it is a protocol designed for long distance, slow connections. So it sends a packet, and doesn't wait for a check. Rather it just sends all packets, and at the end, the recipient sends back a list of bad packets to be resent. The idea is, it will be faster when sent over a high latency connection. I *think* the protocol was created by John Friel. I base that off the little info I was able to find thru multiple different online searches (google being the most useful). What I am looking for is the specs needed to write an implimentation of it. I have a system that can only send files via i-modem, and I want to write a new program to talk to the server. Right now I use Procomm Plus 1.1b since it is the only application that I have found that supports imodem. I would like to write a custom front end to the system, so I can make access safer, easier, and more automated. If anyone has specs, or source code for imodem they can send me, it woud be very helpful. Thanks -chris <http://www.mythtech.net>
