I have had problems with sending files using procomm's ymodem batch. It seems to timeout on the first data block. Has anyone else had this problem?

One of them is a protocol which is really little (or no) more than Xmodem with a 1k block size, properly called xmodem-1k, but many systems call it ymodem. There is something called TRUE YMODEM, which is claimed, by its author, to be the original ymodem. I do not know who is right, etc., and do not want to discuss that, but I felt compelled to let you know that there ARE multiple uses of the name. Therefore, it is possible that the problems you describe are simply due to protocol mismatches, and that if you have the opportunity to experiment with which protocol to use that you might be able to work around it. You might try to pick up a copy of dsz, which implements ZMODEM, TRUE YMODEM, and XMODEM protocols. It is available on many BBS systems as shareware. Good luck! Fred
