Hi all!
I’m writing virtual serial port driver. Originally the project was started as
WDM driver and it is almost done under Win2k. But Win98 uses different
communications driver architecture so no applications see port devices created
by WDM driver under Win98. So now I’m writing separate port driver vxd for 9x.
And my questions are:
- Am I right in starting writing port driver vxd, or may be there is some other
way to make WDM driver work under Win98 (I dont have to support Win95). If
there IS a way to avoid writing port driver vxd, it would be great :))
- When I install new ports (under Win98), my port driver vxd gets loaded and
called appropriatly when port is used by Win32 applications (that use MS Comm
ActiveX or applications that talk directly to communication API). BUT. If DOS
applications uses this port, my port driver NEVER GETS CALLED. It doesnt even
get loaded. I checked out that standard serial port driver (serial.vxd) doesnt
get loaded neither (when port in use by DOS app). What should I do to make my
port driver work with DOS apps too?
- What is vcd.vxd? 95DDK says almost nothing about it. (I add registry entry
Contention = *vcd.vxd)
Thanks in advance,
Vladimir
