I had to do 2 things, 1-tie cts and rts together,2-switched from my old HP laptop that I've been using for the comms and tried my newer Compaq laptop that I've been using to program PICS and for internet.

So now it's working,finally, cts and rts tied together and communicating with a newer pc. THANK YOU!

I do have another question, in the code where achar="A",how can I get more than one letter to work in place of "A" ? Such as something like 8A 45 A0.

Thank you all very much,
Sam
