Hello,
I'm working on a problem which I would appriciate some help on.
I am writing an application for our RF inventory scanners. The scanner itself is basically a telnet session onto our HP Unix system running progress 8.0.
What I am doing is this.
def var vscan as char format "x(15)".
update vscan.
Bell.
The scanner produces a bell after it has read a bar code on its own. Then on the screen you see the number or charaters SLOWLY echoing back. Finally you get the bell generated from this code. This can take from 1 to 5 seconds depending on how far away you are from an access node. (yes I've timed the time between beeps). I am trying to get this time down and my theory is if I have the update be silent I maybe able to save the IO and cut some time.
What I want to do is this I want to update that vscan WITHOUT it echoing back to the screen. Even if it doesn't work for this app it could be fun to know a good technique. Like using it for password hiding on log in's
Does anyone know how to update a variable from user input without the characters being echo'd on the screen?
Thanks for your help on this,
Dave
