I have to use internet over GPRS modem in windows xp and windows 7, so i have created a dial-up connection using Rasdial API
But i get some problems.
that is, when i creat Ras entry by RasSetEntryProperties api, the entry come up with the default maximum speed of 115200 (but i must use other baud rate, for example, 7200000) .
I can edit this manually in the modem settings, but dose anyone know the API's i can use to set it in code?
I don't want to modify registry about modem.
I have looked through the MDSN, but RasSetEntryProperties function dosen't do it, and it says, lpbDeviceInfo param is unused in Windows XP.
Are there any other solutions except modify registry before making ras entry?
