DTR Flow Control

[Michael Cardenas]

Is DTR flow control supported?

There's a comment in comm.c in SetCommState that says it's not, but 
EscapeCommFunction has a SETDTR case and a CLRDTR case.

Below are the lines I'm talking about.

I'm working on an app that asks for DTR flow control and uses overlapped 
IO when using a modem. It establishes a modem connection, but then it 
can't send any data over the connection. I'm using an external modem on 
a serial port.

------------------------------------------------------------------------

if (lpdcb->fDtrControl == DTR_CONTROL_HANDSHAKE)
      {
             WARN("DSR/DTR flow control not supported\n");
      }

comm.c line 1069

-------------------------------------------------------------

case SETDTR:
    	        TRACE("SETDTR\n");
#ifdef TIOCM_DTR
    		direct=TRUE;
    		result= COMM_WhackModem(fd, 0, TIOCM_DTR);
    		break;
#endif

comm.c line 548

I am not at all sure, because I don't know what it is.  Hardware flow
control as understood by the Linux C library is rts/cts flow control.

No necessary connection.  The app can manipulate those signals itself.
Flow control as I understand it is done by the modem and the OS to
prevent overrun of the FIFO and the OS's buffers, behind the app's back,
so to speak.

Probably a logfile from

wine --debugmsg +file,+comm yourapp.exe 2>&1 | tee logfile

would mean more to me than excerpts from code I help maintain.  +relay
never hurts, except it takes so much space, but traces gzip pretty well.
I expect Mike McCormack, the other person who is willing to touch Wine
serial comms, will be along presently.

Attached is the relevant part of the output of +file,+comm.

It looks like the app is using ClearCommError to check for the number of 
bytes recieved. I've read that the TIOCOUTQ ioctl is buggy and not very 
reliable, but I'm not sure if that's been fixed or not in newer kernels.

[Michael Cardenas]

Attached is the output of +relay,+file,+comm.

It looks like ClearCommError is returning 20, which is "ERROR_BAD_UNIT", 
system cannot find the device specified. Shouldn't this be returning 
ERROR_IO_PENDING for overlapped io?

I changed files/file.c to call SetLastError(ERROR_IO_PENDING) after the 
call to read(...) in the FD_TYPE_OVERLAPPED case instead of calling 
FILE_SetDosError, but that caused my app to not even be able to talk to 
the modem to get it to connect, so apparently that's not the problem.

May we see a

wine --version, please?

If I am not mistaken,

FIXME:pthread_rwlock_rdlock
FIXME:pthread_rwlock_unlock

went away 11 December 2001, and were absent from the Boxing Day FTP
release of Wine, which is already obsolete:

wine --version
Wine version 20020122

IIRC, you are using an external modem.  How do you know that it is
connected with a good modem cable?  That it works for Windows means
nothing.  I am reasonably sure Windows simply does not do hardware flow
control at all.  If it works for Linux pppd, I would have more
confidence in it, but I would still check every line with a voltmeter.
Also, the settings of the modem matter.  I have a no-name V.34 that does
what it calls "CTS flow control" by default.  It is essentially unusable
for Linux unless I give it an AT\Q3 to command it to use RTS/CTS flow
control, then it works fine.  Of course, any modem would probably have a
different AT command for that.  If CRTSCTS is set in the termios, Linux
does _strict_ RTS/CTS flow control.

If your modem works with Linux pppd, why would you even want to run a
Windows comms app?  8-D

I'm not convinced the GLE 20 is not a hangover from something that
happened before.

Constants aren't, and variables won't.

My comms apps have been banging on ClearCommError for that since August
1997, but without the overlapped nonsense.  It works for me or I
wouldn't have gotten your letter.  This app appears to ask for
rts/cts flow control - at least that is what we give it.  Dumb
question:  is there a modem cable or null-modem cable involved?  If so,
is it a good one, with wires for each signal (properly crossed for a
null-modem cable), or is it a 3 wire Windows cable?  Wine actually does
use (cause the serial driver to use) rts/cts flow control if the app
asks for it, and it won't work on a 3 wire cable.  I don't believe
Windows actually does hardware flow control at all, no matter what the
app asks for.

I don't really know the overlapped stuff too well, but I would expect
having an overlapped read going on would keep cbInQue at zero:  as soon
as there are bytes available, they get read.  Maybe Windows doesn't do
it that way.  Maybe we don't either.

Mike?

Hmm.. I am pretty sure that Windows 9x and NT do use RTS/CTS flow 
control.  The standard win3.11 drivers don't IIRC, but 95 and above and NT 
always do if you have the hardware flow control radio box checked in the 
properties for the modem (and the app doesn't override it itself).

[SNIP]

One thing I would like to mention is that I think almost all Gateway 2000 
486 computers have an incorrectly wired 25-pin serial port.  DTR is not on 
the correct pin on the 25-pin D connector but is on the correct pin on the 
10pin connector that is on the motherboard (which to my knowledge is the 
same for almost every motherboard that uses this type of serial 
connection).  If you upgraded the motherboard in one of these old cases 
and did not use the new serial ports that came with the new mobo this may 
cause you some trouble.  Fortunately my USR v.Everything has a DIP switch 
setting to turn off DTR control.  The downside is that with DTR turned off 
you cannot just drop DTR to hang up but must instead use +++ATH.  
Fortunately I got rid of that 486 board many computers ago.  
(Un)fortunately I no longer use the v.Everything modem for much since I 
have a cable modem.  It's almost a shame too, it's a really nice modem, 
connects with everything under the sun.

To my knowledge the serial driver of Linux does not support DTR flow
control.

So it might be a bit hard to implement in WINE.

There is an article from Rein Klazes, 
    http://www.winehq.com/hypermail/wine-users/2001/12/0209.html
could you try his suggestions?
