SIM300C problem with connection

[lukee]

Hi,

I have big problem with connection with SIM300C. I have connected SIM300C throught EVB to my PC. I have created new connection at HyperTerminal (19200,8-N-1), but when connect to SIM300C, it haven't send any data.

What is wrong ?

Best Regards
Lukee

Make sure you are using Serial1 and not Serial2[That's for debugging]
