DTR program

[Louis D'Ambrosio]

 To Everyone and Anyone!

    I've gotten involved in a project that requires a "C"
program that can watch a given serial port and wait for DTR
to go HI. The program would then run a script and continue
watching the port for a drop of DTR.   If this occurs it would
kill the script.    


The machine I run on is a Altos 486/1000 w/Unix V v3.1, or
if you really want to get picky Altos Unix v5.3et2.


I have some skill in "C" but this is beyond me so any help
would be appretiated.

Thanks!
