I'm trying to establish GPRS connection in winxp via my phone used as modem on COM3.
I have used CreateFile, ReadFile, WriteFile for sending and receiving AT-commands and it seems to work as expected. However part of the response i get after sending a command is not returned before i send the next command.
The \r\nOK\r\n part i would like to be returned at the end of first reception, but not sure how to do this. I sniffed winxp dialup to see how it is done and it seems to use IOCTL_SERIAL_GET_COMMSTATUS: Retrieve COM status, in order to get last bytes. However I'm not sure how to do this in my program
Thanks in advance
