porting usb modem driver

OSR_Community_User · November 24, 2004, 2:06am

hi,

I was asked to port the existing win2k/xp usb modem driver to windows
98/me(WDM). Now it can be successfully added, but I failed to open the modem
com port to send AT commands or simply use CreateFile routine to get the
handle. I haven’t made any progress on this for almost a month and don’t know
how to proceed.

Because of the license prohibition, I can’t paste the source code here.

If someone has some experience on window 98/me usb modem driver(WDM) and
wanna help me out, please don’t hesitate to contact me through MSN:
xxxxx@hotmail.com

Thank you so much~

Best regards

Jason

hi,
The program is blocked when calling CreateFile, so I couldn’t get any error
code.

Calling the program below, the driver first received IRP_MJ_CREATE, and open
the com port(I dunno whether it is successful, but it returned SUCCESS), then
got IRP_INTERNAL_DEVICE_CONTROL the driver doesn’t support. There is no other
IOCTL, like IOCTL_SERIAL_XXX.

---------- WinMeOpenCom.c -----------------
#include <windows.h>
#include <winbase.h>
#include <winnt.h>

void main()
{
HANDLE m_hComm = CreateFile(“COM4”, GENERIC_READ|GENERIC_WRITE, 0, NULL,
OPEN_EXISTING, FILE_FLAG_OVERLAPPED, 0);
if (INVALID_HANDLE_VALUE == m_hComm)
{
printf(“\n\nUnable to open com port (error %d)\n\n”,
GetLastError());
return;
}
CloseHandle(m_hComm);
}
