Hi
I bought an EM 406A gps module. I want to see the data output in hyperterminal, so I gave +5v and Gnd to relevant pins of the GPS and attached the Tx pin of the GPS to the pin 11 of MAX232, and pin 14 of max232 went to pin2 of rs232 and gnd were made common by attaching rs232 pin5 to gps gnd as well.
Nothing appeared on my hyperterminal. I then realised that TTL level of my GPS module is 0 - 2.85V.
I put my GPS module aside.

I have an already working project where PIC is attached to an GSM modem TC35i. It works fine. As it gets boring when things are working fine so I did an experiment to read the commands PIC is sending to my GSM in Hyperterminal.
My connections stayed the same PIC tx >......Max 232 pin11 & max232 pin14 >......pin2 of rs232. Gnd common, BUT I still couldnīt read anything. I was hoping to see the AT commands PIC is sending regularly.

Please help.
