Hi

I am trying to communicate to a modem via the 8051 microcontroller specifically the (89C51)
However I dont know how to use the hayes commands via the microcontroller to talk to modem.

Could you please suggest to me some useful code which might set the communication link between the modem and 8051 also giving me some additional inormation in this regard.

Whilst thanking you in advance I look forward to ur reply as soon as possible.

Warm Regards

Minal.
