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 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. 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 timein
    the past?

    Mark LaPierre


    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


    Â Paul,

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

    Â Sent from Henry Nee



    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

  What exactly do you want to do with the data?  Capture it, pipe it into
  another program, ??

  In miniterm you should see ttyUSB0 as one of the serial ports available.


  Robert Vanzant

  Many things just recording it would a good start.

  Paul Lamar


I'd apt-get install minicom if you don't already have it.  Use the -s
switch the first time you run it to enter setup mode.  Set the serial
port to /dev/ttyUSB0, fiddle with the baud rate etc, and see what
happens.  As I recall it was somewhat finicky about saving settings, so
confirm that it's actually configured the way you think it is when
trying to listen to the gps.

Looks like it won't work with the version of Ubuntu I have.

Paul:

Since I too have one of the LT-20 GPS on the shelf, and since I run
Ubuntu, you managed to get me playing with mine. I managed to get
minicom working, but so far all I get is an I/O error message

I found the following on a web search.  Too busy today to try it.


Gpsd: Fixing for Ubuntu
September 3, 2008 — digitaleagle

I have an LT-20 Delorme Earthmate GPS.  It may not be the best GPS, but
it gets the job done.  Getting it to work in Ubuntu was no easy feat.

I had to fix a bug in a cypress module.  I followed the instructions
from here.

To get the kernel version, I ran:

uname -r

Then, to install the kernel source, I ran:

sudo apt-get install linux-source-2.6.24

Then, I changed directories into the installation directory and unzipped
the source:

cd /usr/src
sudo tar -xvf linux-source-2.6.24.tar.bz2

Then, I copied the two files:

cd linux-source-2.6.24/drivers/usb/serial/
sudo mkdir /usr/src/modules
sudo cp cypress_m8.h cypress_m8.c /usr/src/modules/

Next, I created the make file (note that I have installed gvim.  I saw a
note saying that they had problems using the gedit text editor):

cd /usr/src/modules
sudo gvim Makefile

And, I pasted these lines into the Makefile:

obj-m := cypress_m8.o
KDIR := /lib/modules/

$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

Then, I edited cypress_m8.c and commented out line 408.  The original
instructions have more detail on this.  I thought the line number might
be different, but it was the same as the original instructions.

When running make (sudo make) I had trouble with “make: Nothing to be
done for `default’.” message.  I just opened the file and deleted and
readded the tab in front of the last line.  Then, it ran fine.

Then, I ran the command:

sudo install -m 644 cypress_m8.ko /lib/modules/`uname
-r`/kernel/drivers/usb/serial/cypress_m8.ko
sudo depmod -a

If you can re- end that in plain text it will work better.
