Package: libserialport0
Version: 0.1.1-3+b1
Severity: important
Tags: upstream patch
X-Debbugs-Cc: t...@seoss.co.uk
Serial port open seems to fail on bullseye. Strace output follows:
1512868 openat(AT_FDCWD, "/dev/ttyACM0", O_RDWR|O_NOCTTY|O_NONBLOCK) = 9
1512868 ioctl(9, TCGETS, {B9600 opost isig icanon echo ...}) = 0
1512868 ioctl(9, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|TIOCM_CTS]) = 0
1512868 ioctl(9, TCGETX, 0x55cd7cc80df0) = -1 ENOTTY (Inappropriate ioctl for
device)
1512868 close(9) = 0
1512868 write(2, "sr: ", 4) = 4
1512868 write(2, "serial-libsp: Error opening port"..., 71) = 71
1512868 write(2, "No devices found.\n", 18) = 18
Applying upstream commit 6f9b03e597ea fixes the issue. I tested this
with:
/usr/local/bin/sigrok-cli --driver=rdtech-tc:conn=/dev/ttyACM0 --continuous
Patch here:
https://github.com/sigrokproject/libserialport/commit/6f9b03e597ea7200eb616a4e410add3dd1690cb1
I suspect that libserialport0 will fail to open all serial ports on
bullseye without this fix, so this bug may unfortunately be RC?
Cheers,
Tim.

Subject: [PATCH] HACK: don't even check for termiox
termiox was removed from linux in e0efb3168d34
Some more information available in
https://www.spinics.net/lists/linux-serial/msg41926.html
Attempting to use the termiox ioctls on more modern kernels results in
"Inappropriate IOCTL" errors.
While the "right" solution might be to remove the termiox code from the
linux path, simply not checking for termiox builds a libserialport that
functions on modern linux kernels.
