This may be of some help to someone trying to figure out the source code. In TestWaveComm.vb, you may wish to add: oGsmModem.ModemInitString = "AT+CMGF=0"
This will set the modem into PDU mode; which seems to be the necessary for when the NewMessageReceived event occurs when receiving a new SMS message.
I'm not sure how one could process this event if the modem is set in text mode, if anyone could advise on this?
Thank you for creating this control - great work! :)
