This program is to control your UMTS PCCard: enter SIM PIN code, send and receive SMS and control/monitor the network connection.

(Dutch and German are nearly 100% done, most other languages
are still non-existent or in early stages)

* improved autodetection
* many bug fixes... read more

umtsmon 0.7 released

The 0.7 release comes with a new autodetection system for the cards. Several new cards are detected and many cards are detected more reliably. The code is also much better maintainable.
Once a card is detected, it will be remembered in the config file.

umtsmon 0.7 also comes with an improved UI and many small fixes that improve the usability of the application - including logging output of a failed PPP connection, notification that a profile needs saving and a new radio preferences dialog.

UMTSmon 0.6 released

Well, this is the 0.6 release of umtsmon... Finally.
Sorry it took so long, apart from everyone being busy, Klaas got into the hospital and we had some hardware issues to fight.

This is probably the stablest umtsmon ever - for all 100% supported cards.
If you own a single port serial card (XU870, GC79, most Sierra Wireless), this release will finally work for you - but don't try to do things with
umtsmon whilst you are connected (like the sms or info dialogs) - umtsmon will crash.... read more

The German Magazine Linux User 2007/03 will feature an article about
UMTS data cards.
Apart from explaining how the hardware works, they also discuss the
Linux software - comgt and umtsmon. The latter even gets its own topic!

What does this mean to umtsmon?

* First of all: recognition from the press: thanks everyone!

we need to work on. part of those (hardware detection / support)
is already on the roadmap, part will be added to the plan soon.... read more

UMTSmon 0.2 released

Hello world,

I just released UMTSmon 0.2.
This new release brings mostly things that are not immediately visible to the end user.

However, umtsmon should not perform much better autodetection of cards - mainly Option cards for now.

There are also command line options now to override autodetection - for example if you are using a mobile phone with USB instead of a PC card.

Happy surfing, and please drop me a line with your remarks!... read more

UMTSmon gets a little attention

UMTSmon is now linked to by and (in the laptop department).

Those two links have generated "massive" traffic to the SourceForge site: 135 hits on the first day, the most since the start of the project.

UMTSmon 0.1 released

The first alpha release of UMTSmon is here.
Most things probably still do not work correctly (like card detection - only 10% of the code is there).

What should work (if you have an Option UMTS card) is:
* SMS sending
* PIN entering
* roaming
* monitoring the connection

If you have any requests for what feature you want first, please send an e-mail to the author!
