It might be worthwhile just *asking* for the protocol. It's unlikely that
WRQ will perceive QCTerm as a terribly serious threat to their main
corporate markets, and they might even perceive it as a marketing
opportunity -- giving you the protocol in exchange for an About-box
credit. There's the Old-WRQ protocol as well; it would serve QCTerm's
purposes quite nicely without compromising WRQ's position at all.

There's also:

4. Use an existing file transfer protocol, like ZModem, which already
supports things like checkpoint recovery. ZModem itself would have to be
modified slightly, at least for uploads, to get around the HP3000's
#$**%#! artificial half-duplex limitation, but it's a starting point.
Also, the code is likely to be available already, either in the public
domain or with a licence that fits QCTerm's distribution model.
