You can download my serial comms test stack from
<http://www.troz.net/Rev/tutorials.php>.
This will allow you to open a port, write to it, read from it and
close the port again.
That should give you enough help to do what you need.

I have never tried it, but I would think that you could have 2 com
ports open at the same time, with a "send in time" routine that reads
from them one after another.

HTH,
