I'm working with a Portwell NAR-5520 (dmesg follows). These machines have
an LCD on the front that uses a serial port to talk to the OS. I've been
having trouble with these:
# stty 2400 < /dev/tty01
...hangs forever...
^Cksh: cannot open /dev/tty01: Interrupted system call
# stty -f /dev/tty01 2400
# stty -f /dev/tty01
speed 19200 baud;
lflags: echoe echoke echoctl
cflags: cs8 -parenb
# python
Python 2.5.2 (r252:60911, Mar 10 2008, 16:28:59)
[GCC 3.3.5 (propolice)] on openbsd4
Type "help", "copyright", "credits" or "license" for more information.
>>> f=open("/dev/tty01", "w")
...hangs forever...
^CTraceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyboardInterrupt
This same stuff works fine running Linux on the same hardware:
[EMAIL PROTECTED]:~# stty 2400 < /dev/ttyS1
[EMAIL PROTECTED]:~# stty < /dev/ttyS1
speed 2400 baud; line = 0;
min = 1; time = 0;
-brkint -icrnl -imaxbel
-opost
-isig -icanon
I can also write messages to the LCD from Linux.
Both OSes detect the same hardware for the serial ports:
OpenBSD:
# dmesg | grep pccom
pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo
pccom0: console
pccom1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo
Linux:
# dmesg | grep 16550A
[ 47.459103] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 47.495182] serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
[ 47.531631] 00:06: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 47.565162] 00:07: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
In both cases, I'm using pccom0/tty00/ttyS0 as a serial console. If I
"stty com1 2400" for OpenBSD at the boot prompt, it sets com0 to 2400 and
I get gibberish on the console until I set my terminal app to 2400.
Does anyone have any suggestions? I'm kinda stumped.
Thanks,
Anthony
