That all looks fair enough.

If all PLCs connect via serial ports whose names match /dev/ttyS*, the
rule I sent you the link for should work for all of them. Hint: If you
want to see what is happening in real-time, open a terminal window and
run the command "sudo tail -f /var/log/messages" and then plug the
PVMCIA card into the computer. You'll see a number of messages appear as
the card is recognised and uDEV configures drivers, etc., and reports
the device name(s) that are assigned. Ctrl-C exits from 'tail' when

If you've used other OSen at the command line level, you may find "Linux
in a Nutshell" helpful because the text in the online manpages is very
(too?) concise. Otherwise you may prefer a rather thicker book on Linux
system administration. This is IMO an over fancy term: many
knowledgeable Linux users and all fully competent Linux programmers have
skills that are reserved for sysadmins on other non-UNIX type systems.
Its not that this is esoteric knowledge, rather that its all stuff
that's very useful to know and all applicable with simple tools like the
command line and a text editor. Did you know that almost all Linux
configuration data lives in simple text files and can be changed with a
standard text editor such as vi, vim, nano or gedit?
