Hi all,
First up, I'm a novice when it comes to UART stuff so please be kind :)
I've been developing on a TS-7550. I've connected the rs232 to an external
controller. By running the following:
xuartctl --port=0 --speed=9600
I can manually type the letter 'a', for example, hit return and the controller
sends a nice big string back to the screen like :xyz123;
But what I really want to do is have a simple shell script that sends 'a' to
port 0 every x seconds, and when it gets the string back it assigns it to a
variable for use by other functions.
I've read all the manuals and scoured the net, but even why I try the suggested
test of something like:
echo "hello world" > /dev/pts/0
it doesn't actually do anything :(
Could anyone possibly point me in the right direction as it's the very last bit
of the puzzle to make my whole fun project work!
Thanks in advance to anyone who can help me with this :)
