Not all permission bits have constants predeclared. Michael and I checked

there must be a reason why minicom uses O_NDELAY (=O_NONBLOCK) in case
O_NDELAY ist defined. Now i remember that i had the same problem several
years ago with cat file >/dev/ttyUSB0, i think it was Fedora Core 3 or 4.
I assume this does not only happen with a pl2303.

Hi Marco,
minicom calls open with O_NONBLOCK and resets O_NONBLOCK directly after
the open call:
open("/dev/ttyUSB0", O_RDWR|O_NOCTTY|O_NONBLOCK) = 3
fcntl(3, F_GETFL) = 0x8802 (flags O_RDWR|O_NONBLOCK|O_LARGEFILE)
f
TFL,O_RDWR or O_NOCTTY);
//AD: non blocking off again
end;

I'm not sure, since this leaves nonblocking behaviour on by defaul

ioctl(3, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS,
{B19200 -opost -isig -icanon -echo ...}) = 0
ioctl(3, TCFLSH, 0x2) = 0
should that be changed in the standard serial.pp ?

Hi Peter,
that is the same as in the standard serial.pp:
Result := fpopen(DeviceName, O_RDWR or O_NOCTTY);
and this fpopen will block as long as minicom is not started on that
device.

I need some hint regarding opening a serial (ttyUSB) port using the unit
serial. Minicom works fine under my user id. When i call
SerOpen('/dev/ttyUSB0'), fpopen blocks forever. When i first start
minicom on that port, SerOpen and all other functions of serial.pp works
fine.
ttyUSB0 is:
crw-r
Start'];
asm
movl$.bss,%eax
ret
end;
any hint on how to do this with the internal asm ?
Thx
