Yes we may be able to use this style with Iyonix and later
hardware, but I think the problem with older hardware was
that serial comms was unreliable until the Block drivers
were used. Particularly for use of a serial modem.
The above may work in RISCOS as
port% = OPENUP "Serial:"
if the appropriate bits of 'Example" have been run first.
while I know this works, I haven't exhaustively tested it.
I have noticed that the 115200 setting gets retained, and
there is no way to set this in CMOS, so it may be that
the block drivers are fully utilised by serial:

Thats interesting, maybe that is the one that the Beagleboard could
use, assuming it talks to HAL for the Serial Port.
I have read that FTDI and Prolific are the two main USB-Serial
adapters used.
While there is Serial hardware to use it is going to be easier.
GPS's and AIS receivers use serial communication but some are being
made with USB adapters for laptops with no serial port.
