I require two delphi functions ( I am using Delphi 6 ).
1) Pass phone number and text (as strings) to TextoPDU function. Function to return completed PDU and Length (for passing via serial port to GSM Modem, this bit I have already implemented)
2) Pass PDU to PDUtoText function and return string(s).
I understand that there are a couple of existing routines out there, but have tried them both, (Barna Szternak's Text2pdu) etc and cannot seem to get them to work.
It is also important to get the length of the PDU back from the function as this is necessary.
thanks in Advance,
