Hi Terry,
I'm planning to make anapplication that has to communicate with an SMS
Modem. I kind of drawned in the lots of bad RS232 code I foudn and tested.
I'm also tempted to do it in VS 2005 because I heard it was integrated
there. Does your code works fine? And did you use the VS 2005 Beta 1 or the
VS 2005 Express Edition? Is it possible to make a working Service with it
that uses RS232?
If you woudl be so kind to paste your code that would be very helpfulltoo
:-)
Thanks a lot in advance,
Pieter
