initialize serial port

[miguel.ossa]

Hi to all!

I have a very strange problem... I am working with a fiscal printer on
Polland, and trying to communicate with it. I have a program in Visual
C++ 1.52, over MS/DOS, that initializes the port using int 14h,
function 00h (the same that does the mode.com command).

I can send any information to the printer using COM1, and the printer
hears me with no problem, but it's not answering to any command.

If I previously execute MSD.EXE, and then I press "C" (Com port
status), then the thing works properly.

Does anybody knows which function I can use to emulate this program?
Or does anybody have another program that does exactly the same
function without interaction with the user? I need to activate the
ports in a public commerce, and I don't want they press "c" and "F3"
every morning in order to work (it's not a clean solucion, isn't it?).

Well, I would appreciate any suggestion... I am leaving Polland this
sunday...

Thanks!!!

Well, if you leave this mythical place called Polland this Sunday, you
have only two mornings left for pressing "c" and "F3" in order to work.
No big deal...

I suggest you ask this question in a group dedicated to Visual C++ and/or
MS-DOS programming.
