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. lawson_whitney(a)juno.com wrote:

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. 08d06170:Call kernel32.CreateFileA(41f4f34c "COM1",c0000000,00000000,00000000,00000003,40000080,00000000) ret=6c11415d

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. Lawson Constants aren't, and variables won't.

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.
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? Lawson ---oof---

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. -Dave

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.
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? Ciao, Marcus
