Hi,

I would like to know how is it possible to have access at the uart to
manage RS232 line (like rxd, txd, dtr) under WIN2000.

Under win98, I found port.dll but this dll is not compatible win2000.

I have maybe to write a dll (low level) to do it.

Olivier.

You cant use rs232 to do anything in win2k. It is a
security hole and isnt allowed. If you are just looking
for a modem controller thats 1 thing but if you are trying
a DOS program forget it.

Hi,

Yes, with a dll, it is not possible to have access at the level 0 of the
protected mode of win2000, but
With a vxd driver I think it is possible.

But I dont know how to write a .vxd.

So I looking for details about that (under masm or VC++)

These links may help explain your options. Note: Windows 2000 is based
