Sending key events to background script
Hi,

short summary:
I need to send keystrokes from USB keyboard to background (bash-)script. I guess I have to use read on the right devive board but how and which?

My details:

I got a small home server with some VMs using KVM/Qemu, all are suse 11.3. But in general I work on a client using a keyboard switch. Additionally, I have a scanner (HP Officejet 6500).

Now I want to send scans into a VM. I did not get the scan button to work but I want to achieve a similar solution. I bought a numerical keyboard with USB connector, connected it to the server and fowarded the port into the target VM.
Next there should be a background process listening to that kayboard and running a variety of scanimage scripts when the numbers are pressed.

I found the keyboard device under /dev/input/by-id/... and probably also under /dev/bus/usb/001/00[1-4]. Unfortunately, the output looks very "raw". I guess there must be an other device to connect to?

Thank you for your help,
Snowman

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
