[GreenKeys] teletype server software

[Henry Minsky]

I recently decided to rewrite the software that drives my Model 28 teletype.
In the house I mostly use the teletype to print out upcoming appointments 
from our Yahoo
calendar.  Yahoo will send email at a pre-set time before the event, and I have
a script that runs when mail is received at a special address, to print out the
message on the teletype.

I decided this time to start with a small lightweight web server which is 
designed for embedded systems, called boa
(http://www.boa.org), and then added in some code to drive the serial port.
When a special URL is accessed on the server (/cgi-bin/teletype.cgi), any 
message
POSTed to that URL is printed on the teletype. The server also runs a 
little command
line monitor for the TTY, so you can type commands to get the weather, 
news, and various other things.
Each of these commands just fetches a pre-defined URL and prints the text 
to the
teletype, so it's easy to add new commands and services.

So, web services, the latest buzzword technology,  meets Teletype technology.

I can put the source code for this up on the web if anybody is interested.
