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.

I did a little experimenting.

apt-get was trying to fetch cutecom_0.20.0-1_i386.deb which is not found
in the repository.  The correct file is cutecom_0.22.0-2_i386.deb.

There appears to be something amiss with your local repo files.  I'm
thinking that they are not updated to match your current installed
revision of Ubuntu.  This happens when Ubuntu is upgraded from one
release to another.

I don't know where Ubuntu keeps the repo files for apt-get but Fedora
keeps the repo files for yum at:

[mlapier@mushroom yum.repos.d]$ pwd
/etc/yum.repos.d
[mlapier@mushroom yum.repos.d]$ ls
adobe-linux-i386.repo        rpmfusion-free-updates.repo
fedora.repo                  rpmfusion-free-updates-testing.repo
fedora-updates.repo          rpmfusion-nonfree-rawhide.repo
fedora-updates-testing.repo  rpmfusion-nonfree.repo
packagekit-media.repo        rpmfusion-nonfree-updates.repo
rpmfusion-free-rawhide.repo  rpmfusion-nonfree-updates-testing.repo
rpmfusion-free.repo
[mlapier@mushroom yum.repos.d]$

This sounds like a similar issue to your apt-get update problem.

I tried it with Real Term on XP and it did not work there
either.
