I have followed the steps in Step 7 MicroWin32 to set up the modems, unfortunately my modems are NOT on included in the list of MicroWin and therefore I have to punch it the modem initialization strings. I am using a GVC 56K modem and I can't find the appropriate init string for it, can anybody help?
Moreover, do I need to program the remote modem (that attached to the PLC) to answer and set up a connection to the the dial-in from the programming station (PC)?
Please send me any material and/or articles on PLC communications via modem.
Any help is appreciated.
