About Modem DCB in DDK 2000

NTDEV
1

Hello,

I am a programmer working on Windows 2K WDM Softmodem development.
I am using a Windows 95/98 prototype softmodem for my reference.

In 95/98 DDK, there is usage of the DCB in toto in “VCOMM_GetCommState()”
and "VCOMM_SetCommState().
The DDK 2K documentation speaks of many structures for sending the DCB ( in
bits and pieces) .

I would like to know whether there is similar support for DCB (in toto - in
a single structure with a single IOCTL) in DDK 2000.

If “yes”, could you inform me about its location in the DDK 2K .

If the same function is not available in DDK 2K, are all of its component
members provided for in DDK 2K ?

Thanks in advance and regards,
Shailender K.

Hi Shailender,

I think that you should download the latest WindowsDDK or MDK at this site.
http://www.microsoft.com/HWDEV/modem/default.htm?RLD=374

Then, it is described to the WindowsDDK help and the document of MDK about
DCB.
And, you are to refer to the Serial sample code of WindowsDDK with I/O
Control code of Windows2000.

Regards,
Makoto

Hello ,

SK> I would like to know whether there is similar support for DCB (in toto - in
SK> a single structure with a single IOCTL) in DDK 2000.

here is no support in Windows 2000 for the whole DCB structure. Some
request set/get some fields from this structure. The serial sample
from DDK is the best reference.
