- The RZSZ version of Zmodem allows a '-e' option on send to 'escape' the
- XON/XOFF characters. This works fine for sending from a Unix machine,
- to a PC running DSZ or GSZ. Unfortunately, DSZ/GSZ can only receive

- compatible with RZSZ. Qmodem might handle it, but I haven't tried the
- upload yet...

- If Kermit is more compatible with it's various implementations, and can
- support XON/XOFF, it may well be the best comm protocol...
