Kermit allows Xon-Xoff handshaking and sends the packet headers in ascii, not binary. This way you never get this deadlock xoff condition. I've had the exact same problem with Sytek Local-Net 20 boxes at a system at Fort Monmouth, NJ.. I needed xon-xoff flow at 9600 and the network units lost characters going to Unix without it. The fix was going to MS-Kermit on the PC (or Procomm's Kermit) and Unix Kermit on the Vax. No problems after the switch to Kermit from an Xmodem based in-house protocol. (The software guys never tested their stuff on the network and no one at the site could figure out what the problem was).
