Do anybody wrote an app. communicating via COM port?
I need to communicate with fiscal printer and electronic cash.

A few months ago I saw a post about communication via COM, but I ca'nt find it (even via search function...)

I've done such thing, but I've used an utility bundled with printer drivers.

That utility can receive a command line indicating the command to the printer or even the complete invoice as a command text file.

So, I've invoked the utility with EXECUTE command and used required parameters.

AFAIK most of fiscal printers comes with some kind of utility.

This way is more easy and reliable for me.

Anyway , there is a library called 'hbcomm' for com port access. From time to time someone ask for it. I'm not fully sure but I guess that it was already posted here.

Hello,

for COM port printer I use normal Clipper commands:
SET PRINTER TO LPT2
SET PRINTER ON ......... SET PRINTER OFF

In autoexec.nt you must add MODE COM1:=LPT2
or you can use command : NET USE LPT2: \\server\printername

I've downloaded harbour 2.0 beta 3, and there is hbwin library, which contains communication via RS.
there is a file contrib/hbwin/tests/testprt2.prg
I want to compile it, but compiler still presents error: undefined WinPort and Win_Port function.

I've added libhbcomm.a (I wrote hbwin as a name of library) in IDE configuration, but compile error still exists...
What's going on?

I think, problem with Win_Port lays in libhbwin.a included in HMG - It's different library!
I've looked into file \hmg\harbour\lib\libhbwin.a and I didn't find any text including "Win_Port" !!!
In \hb20\lib\libhbwin.a such a function is defined!

Could you check it, Roberto?
