----------------------------------
The serial port of my Ultra1 is configured like this:

myUltra1: # eeprom ttyb-mode
ttyb-mode=9600,8,n,1,-

----------------------------------
The tty-section of my "/etc/inittab" looks like this:

#1:2345:respawn:/sbin/getty 38400 tty1
#2:23:respawn:/sbin/getty 38400 tty2
#3:23:respawn:/sbin/getty 38400 tty3
#4:23:respawn:/sbin/getty 38400 tty4
#5:23:respawn:/sbin/getty 38400 tty5
#6:23:respawn:/sbin/getty 38400 tty6

# Example how to put a getty on a serial line (for a terminal)
#
T0:23:respawn:/sbin/getty -L ttyS0 9600 vt102
#T1:23:respawn:/sbin/getty -L ttyS1 9600 vt100

----------------------------------
The serial devices are:

myUltra1: # ls -la /dev/ttyS*
crw-------  1 kap2 tty     4, 64 2005-07-29 13:23 /dev/ttyS0
crw-rw----  1 root dialout 4, 65 2005-02-28 00:37 /dev/ttyS1
crw-rw----  1 root dialout 4, 66 2005-02-28 00:37 /dev/ttyS2
crw-rw----  1 root dialout 4, 67 2005-02-28 00:37 /dev/ttyS3
crw-rw----  1 root dialout 4, 68 2005-02-28 00:37 /dev/ttyS4

I am member of the "dialout" group.

----------------------------------
The print command I tried was:

myUltra1: # cat ~/.bashrc > /dev/ttyS1

----------------------------------
If I overlooked any  necessary information, please let me know. My hope is, that
someone of this discussion group uses the serial port of the Ultra1 (for printing)
and can supply me with his configuration

TIA
