Unfortunately, I am sending files to portable data collection devices that require mainly xModem and Ymodem, and I have to be able to communicate with them, so changing the xfer protocol is not an option. I have used Commtools and it works in Win9X but bombs on Win2K. I am really hoping that CommTools tech support can provide an answer, but I am exploring other options in the event that I have to rewrite.

I just downloaded from http://www.marshallsoft.com/wsc4fp.htm and will test it this morning. It does indicate that it supports the xfer protocols and OS that I am looking for.

Thanks again.
