hi... i just buy this tc35 siemens gsm module.... i encounter some problem when using the AT commands... btw, i using hyperterminal, arduino uno and flash magic to try enter the AT command..... the baud rate is 19200 not 9600 as from the tutorial... the problem is, when the 'at' is entered, i dont get the feedback 'ok' from the gsm module.... but when i call from my phone to the gsm simcard, i got 'RING" feedback from the gsm...
the connection i use to connect the gsm module to the pc is 'siemens tc35' > 'rs232a' > 'uc00a' > pc.... (as from cytron product code)...
pls assist me....
