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

[From: Aleksey Yashchenko]

Thanks Gerard,

It helps me much!
The solution proposed by Winston (to use Bluetooth adapter) is also
good, but its more expensive ($100 vs $19 for USB-Serial).

Does, moreover, if ftdi driver emulates Serial port its just what I
need, because I can change serial port settings thru appropriate API.

Thanks.
