[MACTCL] Serial COmms Works in MAC Tcl

[Ralph H. <rh...@bm...>]

I know it's been done before, but I'd like to extend
a big thank-you to James Ingham and Daniel Steffen for
keeping the faith in Tcl. I have resurrected my Tcl
code and got my LEGO Mindstorms add-on working on a
Mac too!

In case anyone is interested, I was able to get my old
Mac6100/60 working with my LEGO Mindstorms system by
using the Serial Port OSAX 1.2 and a copy of Apple's
Serial Tool.

It's really slow, and really ugly because I can't use
filevents. I have to poll the port using a procedure
that is fired as the result of an "after" even, but it
works!

I know there must be an easier way to do this eventually
but I'm convinced now that port or device access should be
done via the channel architecture.

The fact that /dev/ttyx looks like a file on Unix systems
has hobbled the progress of port access for cross-platform
Tcl applications for too long...

I'll post a URL to my website that gives the details. I'm
pretty proud of the fact that the same script runs on
Mac/Win/Linux machines with minimal platform-specific code...

Cheers, Ralph Hempel
