This is a very desparate plea for help.  I am currently working for a
very small company, and am having a very tough time convincing them that
the documentation which came with the bar-code-reader they just bought
(for a good sum of money) is not sufficient for me to talk with it over
the serial port.  There is no mention of what the data looks like, and
definitely no sample code.  There isn't even a pin-out of the port,
although I'm assuming it is standard 2-3,4-5,7.  (Although the port
on the unit is SCSI, the cable which plugs into it has a standard
RS232 port, with only the above pins, and pin 20, being used)  BTW,
what is pin 20?

The unit is from Symbol Technologies, in Bohemia, NY, USA.
We have the following:
    - Datawell 160 (socket/mount for portable code-reader)
    - LS8560 Scanner (plugs into above)
    - Omnilink LL500-I100 (goes between DW160 and computer

Please, can somebody help me?  Today at work I had to argue with
my boss for 15 minutes before I could convince her that my program
wasn't working because the (above-mentioned) unit wasn't plugged in,
and that we simply needed an adapter to plug it into the wall!
Please, if you can tell me anything about the above unit, preferably
to do with talking to it on the serial port (reading its data), I'd
really appreciate it.
