Anybody know how to take ASCII data in from a USB port using
the Linux command line? I have a USB GPS receiver probably putting out
NEMA 0183 ASCII data every one second.

-------------------------------

When I do "dmesg" I get this among other things.

What do I do now?

Paul,

Try installing cutecom with your package manager. If you use yum:

yum install cutecom

CuteCom is a graphical serial terminal, like minicom or Hyperterminal on
Windows. It is aimed mainly at hardware developers or other people who
need a terminal to talk to their devices.

It appears that the package server was off line.  It failed to find the
cutecom package as well as all the other issues that I SNIPed out.

Try looking for a terminal program using your software installation
utility.  I use Fedora so my example is based on Fedora with the Gnome
desktop.  Ubuntu uses the same Gnome desktop so this might be good.

Go to: System|Administration|Add/Remove Software

In the search box provided type in "terminal" without the quotes.
Select the terminal you want to try and then install it from there.

It is possible that your repository files on your desktop are out or
date.  How old is your current Ubuntu installation?  Have you run an
upgrade from a previous version to the current version at some time in
the past?

I searched high and low for Unbuntu but maybe I need to switch back
to red hat.

My current Ubuntu is a couple of years old.
