Why not use the Radio’s keyer

SkookumLogger must send one character at a time in order to support callsign type-ahead. Keyers built into radios don’t echo anything. So, the software doesn’t know when it needs to send the next character, unless the software does all the speed-dependent timing calculations for each character. Truly ugly, but I did it, and encountered two additional issues:

Tapping a paddle plugged into the radio aborts sending. But, because the computer isn’t informed about the event, it just keeps on sending characters.
In the K3, aborting sending in software is doable, but only if you configure the @ character as stop. However, sometimes when the K3 receives the @ character while sending it stops sending but leaves the sidetone turned on.
