Problem
When connecting a
serial interface adapter
to a server running Red
Hat Linux, SLES, or
HPUX, the numeric
keypad keys on a PC
keyboard do not map to
VT100 emulation under
the Linux shell. Using the
numeric keypad with
the vi text editor causes
function characters to
appear rather than
numbers.
Virtual Media is not
working properly.
Options in the Virtual
Media dialog box are
not available.
The keyboard does not
respond after opening a
Virtual Media session.
The video resolution is
distorted.

Connection length table

The console switch offers optimum video performance when the distance between the server and console
switch is 15 m (50 ft) or less. The system is capable of operation at distances up to 30.5 m (100 ft), at
reduced video resolutions.

Troubleshooting
Use the printenv command to show the TERM assigned under Linux. It can be
matched appropriately with other termcap entries by editing the profile or setting the
TERM equal to "ansi". For PC keyboards, ANSI is the most compatible emulation.
-or-
Edit your /etc/inittab as s0:2345:respawn:/sbin/agetty -h ttyS0 115200, 9600 ansi
Where ttyS0 is the serial device name under Linux where the serial interface adapter
is connected.
At a shell prompt, enter init q, or reboot the system.
Be sure that you are using the following:
Console switches with Virtual Media
A USB interface adapter with Virtual Media, or a PS2 interface adapter with Virtual
Media
A server and operating system that supports high-speed composite USB 2.0
devices
You must be able to see a Virtual Media CD drive and a mass storage drive on the
target server to be able to map a local resource to the remote server.
See Configuring Virtual Media Session settings (on page 44).
See USB 2.0 composite device limitations.
