I used VC to drive installation programs (mainly through INF), use it to install the sound card, network card, USB driver, etc., it can be installed smoothly, and it is always an error when using it to install MODEM driver. Error code For 997, I / O repeat, its error code is IF (! SetupdicallClassInstaller (Dif_RegisterDevice, M_HINFO, & M_DEVINFO) Return getLastError ();
Returning, is it, when you install the Modem driver, what you have to do more than them, if you specify the serial port, how to achieve it.
I hope everyone can point me, thank you! ! !
