You need to do all the settings (including #baudRate:) _before_ you do the 
openPort: . Swap the last two lines.

Instead of using a Stream, a lower-garbage alternative is to use 
SerialPort>>readInto:startingAt: with a pre-allocated buffer. Then you just 
have to keep track of the start position. No String creation is involved!

Anyway, I'm not able to get the sqUnixSerial.c code to work even when I link 
it into a C program. I'm looking into the port settings. I'm wondering 
whether my changes to the Linux operating system (from 2.2.whatever to 2.4.4) 
since the last time I tested this have made any difference. I'm going to try 
it on a 2.2.19 system.
