[Elecraft] High Speed CW issue with dropped characters/delay at high speeds with K3/P3

RE: High Speed CW issue with dropped characters/delay at high speeds with
K3/P3
I've been corresponding with Marc on this and we've made an interesting
discovery. We lowered the port speed and could not duplicate the dropped
characters, although he did experience the delay. I've included his email
response in this post.

Wow, Jer, you may have discovered something important.

I just did a non-exhaustive test of the keyboard with SVGA where the P3 and
K3 are set to 4800 baud.

Not one single dropped character!  This is a first in my experience.

The 4 second (approx.) delay still occurs every 132 (approx.) characters but
that always seemed an unrelated problem.

I'm including Paul Saffren at Elecraft in this e-mail since he has strong
interest in this problem.

The keyboard I used for the test is an Anker wireless.  Now I'll try a Geyes
wireless which Elecraft suspect of being incompatible with the USB library
currently used in the SVGA card.

Yes, RS232, can you check and lower the port speed to see if it resolves the
cw issue?
