Opening serial connection

[Guest zero_divide_1]

Okay, I have no idea how to open serial ports and read/write to them, but I guess now is as good of a time as any. I'm trying to write a homescreen plugin that displays the subscriber's phone number(s) underneath the current operator text plugin. I'm trying to open the "RIL1:" port and issue the appropriate AT command, but for some reason when I do a ReadFile it always results in "0" being the number of bytes read. Can somebody let me know what the correct procedure is for reading/writing to this port? Source code (not for the XDA though) would be appreciated too! Thanx!

isn't there some serial port code in the SDK? seem to remember a project had some in

Well, do you know what the code is to open and write to the RIL1: port? It seems WriteFile and ReadFile don't do anything when I open it:

HANDLE hRIL = CreateFile(TEXT("RIL1:"), GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_SYSTEM, NULL);

if(hRIL && hRIL != INVALID_HANDLE_VALUE) {

   DWORD dwBytes = 0;

   if(WriteFile(hRIL, "AT+CNUM\r\n", 9, &dwBytes, NULL) && dwBytes) {

      char buffer[128] = { 0 };

      if(ReadFile(hRIL, buffer, sizeof(buffer), &dwBytes, NULL) && dwBytes) {

         ...

      }

   }

}

CloseHandle(hRIL);

Just use RIL functions.
