[Bug 19416] New: WINE doesn't recognize pseudo tty's

http://bugs.winehq.org/show_bug.cgi?id=19416

Summary: WINE doesn't recognize pseudo tty's
           Product: Wine
           Version: 1.1.26
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I'm using a software called 'remserial' ( http://lpccomp.bc.ca/remserial/ ) to
remotely access a fiscal printer. The program creaters a pseudo-tty in the
'client' redirecting to the printer in 'server'. I can connect to the printer
with any other application, except WINE.

I read that WINE uses 'setserial' to grab serial port information, perhaps this
is the source of my problems as 'setserial' doesn't work with pseudo tty's.

Here's the output when i try to run setserial on the pty port:

bash-3.1# setserial /dev/pts/2
Cannot get serial info: Invalid argument

When I try to access the port with WINE, I keep getting EscapeCommFunction()==
FALSE errors.

I also tryed to edit kernel32/comm.c and comment out the lines in the
EscapeCommFunction section that tries to obtain serial information. Now the
error doesn't happen but the application doesn't work neither.

Hope it helps.

This is not a bug at all. You requesting something that doesn't even exist on
windows. Please provide the same links to proposed patches you mentioned on
forum.

perhaps you should learn about Windows 'net use' command.

Please point me to where it says anything about ptty.

Com port (or other network device redirection) the way it works on windows has
nothing to do, not even close to what ptty is and how it works.

First of all pty concept doesn't even exist on *NT plataforms. I mentioned 'net
use' cause it make possible to access a printer (even I/O information)
remotely.

FYI: Only WINE cannot print on the remote printer, any other application works
flawlessly.

As I said on the first post, this is probably because WINE uses 'setserial' to
catch port information, then this is more a feature request than a bug at all.

No update for over 900 days. Is this still and issue in 1.5.31 or higher or is
this  abandoned ?

Needinfo/abandoned. Without such a hardware impossible to test. Does the patch
have value?

i can't reproduce this, it works fine in 1.1.44, 1.2.3, 1.4.1 and 2.0-rc4.
Testing is very boring so instructions if I ever need to do this again:

#launch server in a console waiting connection and printing stuff to screen
socat TCP-LISTEN:23000 -

#launch remserial to create the "virtual com" and connect to server
./remserial -d -r 127.0.0.1 -p 23000 -l /dev/remserial2 /dev/ptmx

Ok, now create wine prefix, symlink /dev/remserial2 to com1 and install/open
realterm. Now what you type in realterm appears in socat screen and vice-versa.
