Hi Dave,

Thanks for you thoughts. I believe that the string lengths are the same and the content is constant, but I will need to do some testing to make sure.

My initial thought was to read the string into and 8*String_length array on one serial input port defined at 9600 baud, discard 7 of the array elements and transmit the 8th element on another serial port defined as 1200 baud and loop back.

Actually the above approach may be over engineering it. It might be as simple as reading in the string, retransmitting it and when its done, go get another string.

My reason that I posed the question to the forum is that I suspect that someone has figured this out before, probably with a far more elegant solution than my idea. I just didn't want to re invent the wheel.

Regards, Paul
