This one seems pretty strange to me. ZModem runs pretty well through buffered lines, being an ACK-less protocol. I've done it myself a few times through a packet network, and I've had no problems I can't attribute to other things. "Other things" include, for example, the fact that this 286 box can't handle continuous 2400 bps receiving from 3 async lines simultaneously without burping every couple minutes. The *NIX 2.x versions are in the public domain now, from what I understand, and I've been using them for over 2 years without problems. Most people connecting to this system have MS-DOS machines and use either DSZ or the ZModem built into the Telix package. -- Scott Reynolds = $ cat 'a can of tuna' Enterprise Information System = cat: cannot open a can of tuna scott@clmqt.marquette.Mi.US ..rutgers!mailrus!sharkey!clmqt!scott
