Hi
I have a embedded Linux board that has the following RS232 Serial Port Pinout
2 = TXD
3 = RXD
5 = GND
7 = CTS
8 = RTS
All other pins are NC.
So, this is wired as DCE and has not DTR/DSR/DCD etc.
How do I connect this to SIM300z. I have an Eval Board from Farnell(SIM300-EVB_V2.02).
Can someone recommend a cable that will work (NULL/Crossover?). I want to
use minicom (on Embedded Board ) to test it, though not particular about using minicom.
Also, I am planning to open (/dev/ttyS0) and read /write AT commands.
Thanks
Sunitha
