serial driver port settings in hyperterminal

NTDEV
1

Hello Gurus,

I wanted to use hyperterminal application for my serial driver testing in
Windows2000. Before connecting to the port hyperterminal pops up a dialog
box for port settings but for my serial port it directly connects, so I
can’t change BPS and other settings. I have made my own dll for port
settings instead of msports.dll. I can see the settings from device
manager. Even if I change the registry for SerialPropPageProvider to
msports.dll, hyperterminal still does not show the port settings dialog
box. I looked at hyperterminal’s and Microsoft website but I did not find
any solution there. I compared all IOCTLs with standard driver and made
sure nothing slipped. I also studied the registry settings done by the
standard driver. Does anybody have any suggestion?

Thanks,
Hakim

The port settings in device manager are just global defaults which any
application can ignore. Hyperterm uses its own UI (as evidence by that
the same dialog is used in win9x which didn’t have extensible property
pages like win2000 and beyond does).
