I am writing a software to read the output of a com port of an instrument. The instrument, continuously send its status condition thro its com port. I have developed a program to read the com port data from a pc.
Now, I want to read this com port from a remote pc, using modem. I wrote MSCOMM1.OUTPUT = ATDT & phone number & vbcr
My phone dials the modem which is connected to the com port of the instrument.(Both externam com ports) It connects and the connecting sound stops. But I don't get any meaningful data. Is it necessary for me to implement any modem protocol? Or do I need some soecial modems?
