AT Commands on Solaris
Most Linux systems have a program called minicom installed (or available) which allows direct communication with a modem. I have recently set up a Solaris box which did not have minicom installed so I had to find an alternative.
On my system, the modem was attached to port B so the device used throughout this guide is ‘ttyb’. If you have your modem plugged into port A simply change this to ‘ttya’.
The first thing I had to do was ensure that the hardwire setting in ‘/etc/remote’ was correct. The file on my system showed:
bash-2.05# less /etc/remote cuab:dv=/dev/cua/b:br#2400 dialup1|Dial-up system:\ :pn=2015551212:tc=UNIX-2400: hardwire:\ :dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
As you can see the ‘hardwire’ line already refers to port B (/dev/term/b). If you have a poke around ‘/dev’ you’ll see that ttyb is actually a simlink to ‘/dev/term/b’. If you are using port A ensure this is set to ‘/dev/term/a’.
I then needed to edit two lines in ‘/etc/uudp/Devices’. The last two lines need changing to:
ACU ttyb - Any hayes Direct ttyb - Any direct
Again, set to ‘ttya’ if applicable.
Once this is complete you should be able to run ‘cu -lttyb‘ and see a ‘connected‘ message. At this point you can begin typing in your AT commands! W00t!
Corporate Web Template
Here is my latest free web template ‘Smooth’. This is based around a corporate/business feel but would also be suited to a blog or portfolio site.
The template uses some CSS3 techniques to create a shadow effect on the headings (not supported in Inferior Explorer). As always, the template is totally free to use and comes with the ‘use as you like but don’t blame me’ warranty.

Virtualbox Red Hat Issue
After playing around with Virtualbox, my Red Hat Enterprise 4.7 VM wouldn’t boot and hung at the ‘Ok, booting kernel’ message. This issue arrises when running the SMP kernel. Change the kernel to a non-SMP as a work around to this. This now works in the latest release. Update to the latest Virtualbox to fix!
Adding Extra Memory to the Aspire One
I upgraded the memory on my Aspire One SSD today to 1.5GB. This task has not been made easy by Acer and involves taking the netbook to pieces to slot in your new RAM. I would advise anyone carrying out this tast to view someone else doing it first! I used the video below… Good luck!
