Hardware Debugger Cannot Communicate With HP-10.x OS Serial Port


Record #1873

Problem Title:
Hardware Debugger Cannot Communicate With HP-10.x OS Serial Port


Problem Description:
Platform(s): HP-10.x
Architecture(s): All
Design Step(s): Hardware Debugger
Reference Number: 13186
The Hardware Debugger cannot communicate with HP-10.x OS serial
ports at the time of this release.


Solution 1:

To workaround this problem, your System Administrator must do
the following:

Configure the serial port as a terminal port. This creates a /dev/tty0p0 if usin
g serial port 0 and /dev/tty1p0 if using serial port 1.  It also appends the fol
lowing to /etc/inittab.

a0:3:respawn:/usr/sbin/getty -h tty0p0 9600
a1:3:respawn:/usr/sbin/getty -h tty1p0 9600
Edit /etc/inittab and comment out those getty lines.

Create a soft link to assign /dev/tty00 to /dev/tty0p0.

cd /dev
ln -s tty0p0 tty00
ln -s tty1p0 tty01

To activate those changes, reboot the system or type
init -q
