Anybody know how to take ASCII data in from a USB port using  the Linuxcommand 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.

[337219.194564] usb 2-5: USB disconnect, address 10  [353725.772224] usb 8-1: new full speed USB device using uhci_hcd and  address 2  [353725.976107] usb 8-1: configuration #1 chosen from 1 choice [353726.141383] usbcore: registered new interface driver usbserial  [353726.141398] USB Serial support registered for generic  [353726.141423] usbcore: registered new interface driver usbserial_generic  [353726.141425] usbserial: USB Serial Driver core  [353726.155861] USB Serial support registered for DeLorme Earthmate USB  [353726.155874] USB Serial support registered for HID-COM RS232 Adapter  [353726.155886] USB Serial support registered for Nokia CA-42 V2 Adapter [353726.155906] cypress 8-1:1.0: DeLorme Earthmate USB converter detected

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 froma 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  tored 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.

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.

Paul,

I am sure your Google Foo is as good as it gets but maybe this will help.  I found the following for serial to USB on Ubuntu assuming that you just want the output and not some application actually do something with the data.

-------------------------------------------------------------------------
First plug in the USB-Serial Port adaptor to one of your USB port. Wait for a couple of second, then run dmesg. You should see these message at the end of dmesg output.

usb 1-1: new full speed USB device using uhci_and address 2
usb 1-1: configuration #1 chosen from 1 choice


After that, unplug the device and type lsusb. You will see a list of output similar to this.

Bus 003 Device 001: ID 0000:0000
Bus 002 Device 007: ID 03f0:4f11 Hewlett-Packard
Bus 002 Device 006: ID 05e3:1205 Genesys Logic, Inc. Afilias Optical Mouse H3003
Bus 002 Device 004: ID 15d9:0a33


Plug in the USB-Serial Port converter back, and run lsusb again, and you shall see an additional line, like this.


Bus 003 Device 001: ID 0000:0000
Bus 002 Device 007: ID 03f0:4f11 Hewlett-Packard
Bus 001 Device 002: ID 4348:5523 --- --- --- (notice the additional line!)
Bus 002 Device 006: ID 05e3:1205 Genesys Logic, Inc. Afilias Optical Mouse H3003
Bus 002 Device 004: ID 15d9:0a33


Now we know the vendor id and the product id of the USB-Serial Port converter, this will enable us to load the linux kernel module usbserial to activate the device, like this :


sudo modprobe usbserial vendor=0x4348 product=0x5523


Run dmesg again and you shall see lines similar like this :

usbserial_generic 1-1:1.0: generic converter detected
usb 1-1: generic converter now attached to ttyUSB0
usbcore: registered new interface driver usbserial_generic


As you can see, the new serial port device is mapped to /dev/ttyUSB0. Youcan instruct Ubuntu to load this module automatically by include the line : usbserial vendor=0×4348 product=0×5523″ inside /etc/modules file.


Then you may be able to use tail -f /dev/ttyUSB0 to read the output.

David and all,
Please send everything in plain text in the future. html screws everything up.
