Thanks for the reply.  I resolved the problem.  I had to put pacing
logic into the multipart messages.  After the first part is sent the
transmitter waits for a message acking that part and then sends the
next part.  This is working correctly for the stage of testing I am at -
Single "transmitter", "Single receiver", but I have all
the logic in
to handle multiple transmitter/receivers.  The application is a "many
to one".  The many are in wall touch screens, the one is actually
homeseer.

A touchscreen can request Homeseer to run a script which returns a
result (e.g. get the current weather for a given zip code.) The result
may be on the order of 2000-5000 bytes, hence the need for multi part.
Also had to encode the text to remove carriage returns (chr(13)) and
Line feeds (chr(10)).  Since on PC's they always come as CRLF, each
CRLF is replaced by "~" before transmission, and returned to CRLF
after
received.

I now have a new problem that I am going to start a new posting on.
Perhaps you will be able to assist me with that.
