I've included this program because the VAXNET program now supports this protocol and you may wish to use this program instead of the SNDRCV program for file transfers. The XMODEM protocol has better error checking than the SNDRCV protocol but only allows sending or receiving a single file at a time. It also has the advantage of running on UNIX where the SNDRCV program does not. WARNING: Receiving files from the VMODEM program works just fine (doing a VAXNET GET command). But sending files to VMODEM has lots of overhead since it does single character reads. At slow baud rates this isn't too bad but at higher baud rates it eats up VMS.
