Help...again!

Archiver

Hi

Ok, I followed the advice Tracy gave, and it worked... So, I was
sending data from the basic stamp to the tranciever, and looked at the
result in another transceiver to see if it sent the data... it did!

Ok, so, then, all happy and all, I went to the next stage... I built a
circuit for the computer that would take in the transmitted data,
convert to RS232 and connect to a serial port connector. Pin 2 is
connected for the data into the computer and pin 5 is grounded. The
rest of the pins for the serial connector I did not touch. please
note, that there is NO basic stamp on the computer end (can't afford
it for our budget)... so, we were hoping this C program would help us
in outputting the data...

The C program that I am using is the following... however, when I
tried my system out.. I got NOTHING on the computer side (ie, nothing
printed on the screen)... can someone tell me what am i doing wrong?

Thanks... now I gotta go to class...
