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. Ã?? It failed to findthe
cutecom package as well as all the other issues that I SNIPed out.

Try looking for a terminal program using your software installation
utility. Ã?? I use Fedora so my example is based on Fedora with the Gnome
desktop. Ã?? 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. Ã?? How old is your current Ubuntu installation? Ã?? 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.

Paul Lamar


Paul,

Since you are using Ubuntu, I would suggest using gtkterm. You should be
able to get it via synaptic package management.

I have read the whole thread.... minicom is the standard text based
terminal for communications.
It used to be part of the minimal install of fedora back in the modem
days. Now you have to add it.

If I send the GPS to you can you get it to work?

Paul Lamar



What kind of GPS?
Blake C. Lewis


Some kind of USB connected GPS Delorme ships
with their moving map software for windows.

It is a ASCII NEMA 0183 protocol. Once a second.

This will allow a remote mount of the antenna for a moving map
program in an Android tablet running Honeycomb. XWing for example.

Paul,
Try 'tail -f /dev/ttyUSB0'

I will play with mine tonight.
Blake

Wow! Something happened. With the GPS unplugged it comes back with no errors.
With it into the USB connector plugged in it comes back with a blinking cursor at the same
one second rate as the blinking led on the GPS.

paul@paul-desktop:~$ tail -f /dev/ttyUSB0
tail: cannot open `/dev/ttyUSB0' for reading: No such file or directory
tail: no files remaining

paul@paul-desktop:~$ tail -f /dev/ttyUSB0
blinking cursor

You are getting warmer.
