[comp.protocols.misc] xmodem, ymodem, zmodem specs.

I am looking for specs. on the modem protocols - xmodem, ymodem, zmodem.
Something that simply explains them will be okay. References to good books
will be good also. I have implemented xmodem using a line monitor and a
paper written by Kelly Smith, CP/M-NET "SYSOP" on January 8, 1980. I don't
know where the paper came from. It does not cover ymodem and zmodem, however.

Thanks.
