Forgive me for being ignorant, but what is YModem?  Is it a standard, or just
something that the author of Red Ryder thought up?

Thanks.

	Ymodem and Zmodem are spinoff's of Xmodem and attempt to correct
various problems, the major one being the fact that Xmodem always rounds the
file up to the next 128 byte block.  They are supposedly upward compatible
from Xmodem. (e.g. Xmodem can't receive Ymodem, buy Ymodem can receive Xmodem)
