[maemo-developers] Connecting RS232 devices to N800 hosting OS2008

[From: Gerard Sequeira]

I think the SILABS converter is based on the ftdi chipset. Fanoush on
www.internettablettalk.com had released a set of drivers compiled for
OS2008.

insmod the driver, run dmesg | tail to see if the converter got detected.
You can talk to the serial chip via /dev/ttyUSB0.
