Hello misc@,
I have a problem with uplcom(4). Whenever I connect to a remote terminal
with "cu -l /dev/ttyU0", it hangs after a few seconds (usually under 2
minutes).
I tried various settings and still have the same issue :
- using /dev/cuaU0
- setting speed 9600 or 19200
- connecting to a Soekris Net5501 or a Cisco router
- using OpenBSD 4.6, 4.7 and -current
However the adapter works like a charm from a MS Windows workstation.
Here is what a typical session looks like :
------------------------------------------------------------------------
# cu -l /dev/ttyU0 -s 19200
Connected
OpenBSD/i386 (soekris.my.domain) (tty00)
login:
[] <= when it hangs the cursor stands here (looks like a \n\t)
------------------------------------------------------------------------
I can't stop cu without killing its process.
/var/log/aculog tells :
------------------------------------------------------------------------
root (Sun Aug 29 21:01:37 2010) <cu19200, /dev/ttyU0> call completed
root (Sun Aug 29 21:14:41 2010) <cu19200, /dev/ttyU0> call completed
------------------------------------------------------------------------
And ps looks like :
------------------------------------------------------------------------
[...]
22347 p0 Is 0:00.01 -ksh (ksh)
27473 p0 I+ 0:00.01 cu -l /dev/ttyU0 -s 19200
5241 p0 I+ 0:00.00 cu -l /dev/ttyU0 -s 19200
[...]
------------------------------------------------------------------------
I tried to enable debugging in /usr/src/sys/dev/usb/uplcom.c but it is
not really helping.
Is there anything I can try to track that bug ?
Thank you in advance,
Denis
P.S. : Here is my dmesg :
