using tip problem

Bouda16 — Thu, 27 Sep 2007 04:45:00 GMT

Hello
I'm trying to access other system connected to my UNIX Tru64 via serial cable, but without any success :-(

I added to /etc/remote following line...
xxx:dv=/dev/tty00:br#19200

But when I try...
# tip xxx
/dev/tty00: No such device or address
fstat error: Bad file number
tip: Cannot stat tty file

What's wrong?

Thanks in advance for any help.
Regards
B.

It complains about /dev/tty00 does not exists. Normally it should, so please post the output of:

ls -la /dev/tty00
crw-rw-rw- 1 root system 35, 0 Aug 23 15:08 /dev/tty00

You can also do:

hwmgr -view hierarchy |grep serial

To identify if you have serial ports. Some systems, like ES47/80... does not provides serial ports.

Hello,

I think this is not the problem...

# ls -la /dev/tty00
crw-rw-rw- 1 root system 35, 0 Aug 9 10:16 /dev/tty00

# hwmgr -view hierarchy |grep serial
38: serial_port tty00
40: serial_port tty01

What do you get if you run:

file /dev/tty00

Can you try with /dev/tty01?

# file /dev/tty00
/dev/tty00: character special (35/0)
# file /dev/tty01
/dev/tty01: character special (35/1) ACE_SLU #0 terminal #1 modem_control off

Your output from file tty01 match my output for tty00, so I think that on tty01 should work. Can you try that?

Now how to fix tty00?, maybe removing the device file and running:

cd /dev
./MAKEDEV tty00

Yeah, you are right if I use /dev/tty01, it looks much better...

# tip xxx
can't open log file
: unknown variable
: unknown variable
connected

Use a like like this:

serial1:dv=/dev/tty01:br#9600:pa=none:

Verify that you don't have any non printable characters on the file with:

cat -e /etc/remote |grep serial1

Check for ^M or something that may cause tip to get confused.
