Hi

I am trying to communicate to a modem via the 8051 microcontroller specifically the (80C32)
using hayes commands instructions.

However it seems that the modem is not responding at all to the hayes commands sent to it via the microcontroller.

Could you please suggest to me some useful code which might set the communication link between the modem and 8051 whilst giving me some additional hints.


Whilst thanking you in advance I look forward to hearing from you.

Yours truly

Anton Vella
