@darius all these folks raving for Zmodem - yes it was better, it also didn't exist till a few years later. I contributed to a few Kermit projects, porting Kermit65 from Apple ][ to Atari 800, hacking on MS-DOS Kermit, porting C-Kermit to Atari ST. And later porting Zmodem to ST as well.
But we got TCP/IP over serial lines (Using MIT SL/FP, not SLIP) and I ported the KA9Q stack to my ST and left Kermit & Zmodem behind. Ftp ftw!
