Hi,
I am trying to interface the msp430-p2618 with the Siemens MC45 GSM modem. The first problem i face is that the msp430-p2618 board has a female DB9 connector and the siemens mc45 also has a female db9 connector. I used a null modem connector with gender changer to connect both the devices but when i send an AT command the response doesnt come back to the msp430. I tested these two boards individually and they both can talk to a pc via a straight cable. What am i missing here ?
Cheers,
Surya
