Well, of the Torches I've got, four have their own serial ports -
the Torch network stations[1] - and only one doesn't - the Torch
Hard Drive system[1]. That would suggest to me the other way round
- Torch boards with their own serial port are common, and the ones
/without/ their own serial ports are not very common.
