[Elecraft] K3 with Writelog communication setup

[Josh Fiden]

I'm debugging some communication issues between Writelog and K3 when the 
RS-232 connection is routed through my power amp. Things mostly work, 
but intermittent errors. Can someone please advise correct (or 
preferred) Writelog settings? It would be a big help to eliminate 
possible cockpit error.

Here's what I have:

Writelog > Setup > Ports > Port setup tab

Set correct COMx port number & select CW button.
Rig type = Elecraft K3
Baud rate = 38,400
Poll? [check box - what does it do?]
Comm PTT = YES or NO or SYNC [what does this mean?]
All Mode PTT on RTS? [check box - what does it mean?]
DVK type = Windows sound board
CW keyer type = PC generates

Writelog > Setup > Ports > CW PTT tab

PTT Control (CW mode ONLY) = {None; Command rig on COMM port; On LPT 
pin16/COMM RTS} [Pls explain?]
PTT to CW delay = 0 msec
CW PTT Tail = grayed out

Thanks & 73,
