U:fon runs OpenSolaris

This entry is not about close encounters of third kind, what one can think after reading the title, this entry is about a new mobile internet provider in Czech Republic called U:fon. His offer includes two internet (CDMA) connection options with theoretical download maximum of 153kb/s and 3.1Mb/s. Yesterday and today I had a chance to try the first option. The package from ISP included a phone with integrated USB modem (see below). Note that the faster option includes small modem integrated into USB stick, but it's more expensive.
After connecting the modem it showed up as AXESSTEL CO., LTD. DATA MODEM. Unfortunately the modem likely doesn't conform to USB ACM/CDC specification and class driver doesn't attach. Anyway it didn't stop me from exploring it. It was a question of few attempts to identify bulk data in/out endpoints used by modem to communicate with the host. While playing with the modem via ugen driver, it surprised me that it doesn't support such basic command like "ATI". Well, I don't mind if dialing works. The PPP configuration for U:fon was almost same as I did in the past for mobile internet from O2. The difference was username/password which is simply ufon/ufon. Unlike one of the sources on the internet, which described manual DNS configuration, I found that the PPP server provides DNS records, so I took advantage of pppd's usepeerdns option.
Beta driver package for OpenSolaris
I added basic support for AXESSTEL modem to my package, which is provided as is. If you are U:fon subscriber and want try the connection from OpenSolaris distribution, you can download the package and follow the instructions from my previous CDMA entry. I haven't done any serious speed test. My download speed was somewhere between 1-100 kb/s, due to variable signal quality. The best ping I achieved was around 350 miliseconds.
