WiFi PDA Meets Linux--Part 3 - page 5
Setting up a New User
One thing the Skype folks have done is make the Pocket PC and Linux notebook look and feel of the interfaces almost exactly the same. This is good because if you know how to use Skype on one platform, the techniques can be transferred to the other. One difference I did notice was that the Pocket PC version has the tabs at the bottom of the main Skype screen, where as the Linux version has them at the top.
Setting up a new user is done exactly the same way, as with the iPAQ.
Placing a Call
Calling another user is accomplished by entering their Skype username and clicking the big green and white phone button. You can terminate the call with the red phone button.
You might also want to investigate the instant messaging (IM) feature. Highlight the user you like to IM and click on the orange "A" button. A screen will appear where you can input your text. Hit the Enter key to post the message. The message will go through to the other person, even if you aren't in a call.
I tried sending a file from my notebook to my iPAQ, but it didn't work. I'll have to investigate further. That was really the only problem I had.
