I know the world of computing has forsworn manuals
for a variety of reasons, but it's a valid approach in
Plan 9.

So, read uart(3) first. It explains how to configure
a uart by opening the ctl file and writing simple
strings. You read and write it by reading and writing the
data file. As they used to say on a game show here,
"that's all there is to it".

If you need more, then try

src con

the source of the terminal emulator.

i would like to write a simple plan9
program that i can use to pull serial
data from a microcontroller based data
logger that i have constructed. does
anyone know where i could find some
sample code that shows how plan9
handles serial port I/O.
