slow keyboard response

krazyideas

I am using the keyboard to tweak things in my progam but the keyboard respons slowly??
How could I speed it up.

I am calling the newkey object from the keyboard program in the library.
Thanks

I think you want to use getkey, as newkey clears the key buffer and then waits for a keypress. Getkey just gets the most recent key, waiting if there is none. Please read the source of the Keyboard object as it contains useful information.

The newkey routine in the keyboard driver is quite fast. It will supply characters as fast as it receives them. There may be something else in your program that's slowing it down. You'd need to post your program as an attachment to a message in order to get more specific help.

If your program takes a while to get back to the newkey routine, that would be the limiting factor since the keyboard driver can't save up typed characters (since newkey clears them out).

Ok wells here is the progam that I have that is giving me a slow reponse.· What I gathered from the responses I have gotten is that the reason it respons so slowly is the leagth of the program.

But here it is

Thanks

The slow down is probably due to all the "term." statements. They probably produce 30 or 40 characters each of which take at least 1ms to send at 9600 Baud.
