[Elecraft] CW sending using the CAT KY command

[Julian (G4ILO)]

I'm having trouble implementing CW sending by CAT in K2Net. According to 
the docs, you can only send 24 characters at a time using the KY command. 
The trouble is that the K2 doesn't automatically report when the buffer is 
empty so that I can fill it with more text.

To work around this problem, I have a timer send a KY; command at 500ms 
intervals. According to the docs, in extended response mode this will 
return a value of 0 when the buffer is full, 1 when it is 75% full and 2 
when it is completely empty. However, what I appear to be getting is a 
response of 0 until all the text has been sent, then a response of 2. 
Because I can't top up the buffer with text before it becomes empty, there 
is an unacceptable gap in the sending every 24 characters. Am I going about 
this the wrong way?

Hopefully Wayne or Eric will respond to this, but as others have also 
written remote control software for the K2 perhaps they have some ideas 
too.
