[Bug 59290] New: Serial baud rates above 115200 not supported due to bug in serial.c
by WineHQ Bugzilla Feb. 6, 2026

Feb. 6, 2026

http://bugs.winehq.org/show_bug.cgi?id=59290 Bug ID: 59290 Summary: Serial baud rates above 115200 not supported due to bug in serial.c Product: Wine Version: 11.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: serial Assignee: wine-bugs(a)list.winehq.org Reporter: winehq.x4aeq(a)simplelogin.com Distribution: --- Hi, I have been attempting to move my simulator from Windows to Linux and have had great success with the exception of certain USB-over-serial devices. I found some references to this bug in the past, but it seems it was never opened formally and bad advice was given: https://forum.winehq.org/viewtopic.php?p=139497#p139497 This bug will affect all applications that interact with devices that run at bauds >115200 (specifically, in my case, 250000), 3d printers, GPS receivers, OBD interfaces, etc. Through much troubleshooting and fact-finding I narrowed it down to these two lines in `serial.c`: https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/ntdll/unix/serial.c#… https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/ntdll/unix/serial.c#… An application that is affected: https://github.com/tronicgr/AMC-AASD15A-Firmware/blob/master/Thanos-utility… sha1: 0ded8cf5b1595a984144b5d5c8dcdaced0020b1e AMC_Config.exe Another application affected: https://www.simhubdash.com/ The applications (AMC_Config.exe is an example of one, SimHub is another) are non-functional when trying to access these USB devices, as they use the API `SerialPort.Open()` which in turn calls `GetCommProperties()` which calls this `IOCTL_SERIAL_GET_PROPERTIES` function, we see these items in the debug log: ```sh 0a48:trace:comm:serial_DeviceIoControl 0x3cc IOCTL_SERIAL_GET_PROPERTIES (nil) 0 0x6acf6b0 64 0x7ffffe7ff4f0 0a48:trace:comm:serial_DeviceIoControl 0x3cc IOCTL_SERIAL_GET_MODEMSTATUS (nil) 0 0x6acf768 4 0x7ffffe7ff4f0 0a48:trace:comm:get_modem_status 0006 -> ``` They applications are expecting to be presented back the actual maximum baud rate - but are erroring out with: "Max baud supported by device 131072" - this correlates to `BAUD_115200` hex value of `0x00020000`. I created a patch as below, instead using the actual max baud supported by Microsoft which is `BAUD_USER` / `0x10000000`, I also added the other supported baud `BAUD_128K` as a SettableBaud for those devices. https://learn.microsoft.com/en-us/windows/win32/api/winbase/ns-winbase-comm… Patch: ``` diff --git a/dlls/ntdll/unix/serial.c b/dlls/ntdll/unix/serial.c index 7a79dd0ac6a..a8585bbced9 100644 --- a/dlls/ntdll/unix/serial.c +++ b/dlls/ntdll/unix/serial.c @@ -376,14 +376,14 @@ static NTSTATUS get_properties(int fd, SERIAL_COMMPROP *prop) prop->ServiceMask = SP_SERIALCOMM; prop->MaxTxQueue = 4096; prop->MaxRxQueue = 4096; - prop->MaxBaud = BAUD_115200; + prop->MaxBaud = BAUD_USER; prop->ProvSubType = PST_RS232; prop->ProvCapabilities = PCF_DTRDSR | PCF_PARITY_CHECK | PCF_RTSCTS | PCF_TOTALTIMEOUTS | PCF_INTTIMEOUTS; prop->SettableParams = SP_BAUD | SP_DATABITS | SP_HANDSHAKING | SP_PARITY | SP_PARITY_CHECK | SP_STOPBITS ; prop->SettableBaud = BAUD_075 | BAUD_110 | BAUD_134_5 | BAUD_150 | BAUD_300 | BAUD_600 | BAUD_1200 | BAUD_1800 | BAUD_2400 | BAUD_4800 | - BAUD_9600 | BAUD_19200 | BAUD_38400 | BAUD_57600 | BAUD_115200 ; + BAUD_9600 | BAUD_19200 | BAUD_38400 | BAUD_57600 | BAUD_115200 | BAUD_128K | BAUD_USER ; prop->SettableData = DATABITS_5 | DATABITS_6 | DATABITS_7 | DATABITS_8 ; prop->SettableStopParity = STOPBITS_10 | STOPBITS_15 | STOPBITS_20 | PARITY_NONE | PARITY_ODD |PARITY_EVEN | PARITY_MARK | PARITY_SPACE; ``` I am unsure how to go about contributing such a small change - I have read the contributor documentation and have the code to fix it, but I am more than a little intimidated.

[Bug 52592] New: MilkyTracker does not work: no valid waveout devices.
by WineHQ Bugzilla Feb. 6, 2026

Feb. 6, 2026

https://bugs.winehq.org/show_bug.cgi?id=52592 Bug ID: 52592 Summary: MilkyTracker does not work: no valid waveout devices. Product: Wine Version: unspecified Hardware: aarch64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winmm&mci Assignee: wine-bugs(a)winehq.org Reporter: carlo.bramix(a)libero.it Distribution: --- MilkyTracker is an multi-platform music application for creating .MOD and .XM module files. https://github.com/milkytracker/MilkyTracker Unfortunately, it doesn't work on WINE because it cannot open any waveout device. Sources of MilkyTracker do these actions: 1) waveOutOpen(&hwo, WAVE_MAPPER, &format, 0, 0, CALLBACK_NULL); This call is a success and it returns a valid handle. 2) waveOutGetID(hwo,(LPUINT)&waveOutID); This call also returns success and it returns a value of 63 into "waveOutID". BUT THIS IS WRONG. "waveOutID" should be equal to WAVE_MAPPER, which equal to -1, as you can see in point (1). 3) waveOutGetDevCaps((UINT)waveOutID, &waveoutcaps, sizeof(waveoutcaps)); As result, this call to waveOutGetDevCaps() fails with return value of MMSYSERR_BADDEVICEID. Here there is the point where there is the code that I'm talking about: https://github.com/milkytracker/MilkyTracker/blob/4f97b7011b20519890e30368e… The cause of the trouble is the way the function waveOutGetID() is implemented. waveOutGetID() calls WINMM_GetDeviceFromHWAVE(). And WINMM_GetDeviceFromHWAVE() calls WINMM_DecomposeHWAVE() Into WINMM_DecomposeHWAVE(), there are these lines: ULONG32 l = HandleToULong(hwave); *device_index = l & 0xFF; But this is wrong, because *device_index will be never able to return -1 that is the value for WAVE_MAPPER. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
