serial port on Sparc

[Jecel Assumpcao Jr]

Has anybody ever used a serial port from Self on a Sparc machine? I 
tried the obvious (opening a unixFile named "/dev/cua/b") but seem to 
have permission problems. I didn't try running Self as root.

Since I needed results quickly and noticed that Squeak had a SerialPort 
class, I got that to work easily enough. But I would really like to 
continue developing in Self if possible.
