The subject of Chuck Forsberg and Zmodem is an interesting one, but I'll leave the folklore for another post.
Tonight I compiled up an ancient version of sz/rz and got an old Windows terminal program called Hyperterm Private Edition working on my Windows XP box.
Hyperterm is both a serial terminal and a telnet client, and has a nice dialing directory and a pretty fair set of terminal emulations, though I only had time to try vt102. It also has a full suite of up/download protocols, including kermit, and x/y/zmodem.
My first tests of zmodem over telnet were quite successful, and it was like old home week. It really brought back some great memories, and terminal based file transfer is a good capability.
Time for bed now - tomorrow I'll do a better job of optimizing the zmodem programs and install the binaries and manual pages.
Maybe I'll do kermit next.
