[Pythonmac-SIG] Detecting serial devices

[Pascal Oberndoerfer]

Hello all.

It's (again) about detecting currently available serial devices (like
modems, IrDA, RS232) on MacOS X.


Dan Grassi at dan@grassi.org:

This made me indeed curious. So I finally had a small utility that prints a
list of available devices including a device's name, basename, suffix,
Callout device file, and Dialin device file.

The source is 'SerialPorts.sit' at:

[It's derived from some Apple sample code. I know it's a mess, but I have
never done any C or Objective-C before. So feel free to flame me about
programming style etc. ;-) Dan: if you would like to improve this, please do
so! Thanks!]

If you run it from outside ProjectBuilder you must open Console
(/Applications/Utilities) first.

My problem is: how can I wrap this snippet so it is accessible from
Mac(ho)Python 2.3?

Or is there any interest in making the complete IORegistry API available in
a systematical way (via bgen, as Jack suggested off list)? Or maybe other
parts of IOKit as well?

Any help very much appreciated,

Pascal
