Add a modem

[ebaichtal]

What is the best approach to add a modem in Windows XP/Vista using InstallShield 2008?

I write InstallScript code, etc. and if that is the best way, just point me at some functions, thanks!

Any place to start with InstallShield? Or do I have to write a separate app to install the modem driver?

I used this piece of code to load a USB dongle which required a specific driver. So you will need to replace the appropriate parameters for you modem.

Let me know if this works for you.

external prototype BOOL NewDev.UpdateDriverForPlugAndPlayDevicesA(HWND,         // HWND  hwndParent,
                                                                 BYVAL STRING, // LPCTSTR  HardwareId,
                                                                 BYVAL STRING, // LPCTSTR  FullInfPath,
                                                                 LONG,         // DWORD  InstallFlags,
                                                                 POINTER       // PBOOL  bRebootRequired OPTIONAL
                                                                );

function OnFirstUIAfter()
        STRING strFileName;
        STRING strTemp;
        NUMBER nResult;
        NUMBER nHwnd;
begin
        strFileName = WINSYSDIR ^ "NewDev.dll";
        strTemp     = WINDIR ^ "INF\\DS24902k.inf"; 
        nResult     = UseDLL(strFileName);
        if (nResult = 0) then
            nHwnd = GetWindowHandle (HWND_INSTALL);
            bResult = UpdateDriverForPlugAndPlayDevicesA(nHwnd, 
                                              "USB\\VID_04FA&PID_2490",
                                              strTemp,
                                              1,
                                              NULL);
            UnUseDLL(strFileName);
        endif;
end;

Hmm this looks good. But I will need to install the modem INF file, and also tell it what COM port to use. (And probably design a dialog box to ask for that, but I've got that part down.)

Don't suppose there is a pre-existing function for taking a COM port parameter? Or modem specific INF installation in InstallShield?

I've looked through a lot of various places on the net, and found rundll32.exe calling modem.cpl, but can't seem to make it work in XP and Vista to point at a COM port.

I just need to install an existing modem driver and point it to a COM port that a user selects. I'm sure people have done it before, but what is the simplest/common method?

Found the solution: http://support.microsoft.com/kb/304294
The Windows DDK (now WDK) is needed to compile it.

And then do a LaunchAppandWait with: "mdminst c:\mdmgen.inf COM3 mdmgen336"

There ya go.
