K2/K3 - KY Command

[Simon (HB9DRV)]

Hi,

With the KY command - how big is the buffer in the K2? I know that I can
send up to 24 bytes per KY, can I send KY repeatedly to load up 100
characters?

While sending the KY buffer how to I stop sending and clear the buffer?

(Guess who's writing a new CW program?)

I wrestled with this when I wrote my K2 remote control program and as
far as I can remember, no you can't. You can send 24 characters and
then you poll the K2 by sending "KY;" and test the reply back to find
out the buffer state. I think it sends 3 values, to say whether it is
empty, full, or able to accept another 6 characters. So you send 24,
then keep topping it up 6 at a time until everything is sent.

To stop sending and clear the buffer, if I understand my totally
uncommented code written 3 years ago, you send "KY @;".
