Hello Dennis,

I don't know if Dave is online now, so I thought I'de jump in and answer your 2 questions real quick...As Dave has helped me immensely on the same serial in out topic...Thanks again Dave!

1) The $d $a is a "Carriage Return - Line Feed" terminator
2) Yep, the hardware ports have to be used for HSERIN/OUT.

Hope I helped and didn't offend you Dave

Enjoying this thread, and learning from it too!
