Serial Package for Mac OsX

[Jim Gurnavage]

Anyone have a working serial package that will allow you to talk to a serial
port in OsX?  ctb (communications tool box) is not supported in OsX, and if run
in the classic mode (OS 9 mode), ctb.Open() will crash the interpreter.

If not, can the CTB package be built under OsX; that is, is it worth the effort
for a total newbie Mac developer and Python developer like myself to attempt to
climb the learning curve to get CTB to work on OsX?

On a similar vein, is there any real platform-independent device I/O library for
python (specifically, to access a serial I/O device such as a modem)?

Thanks,
