[Elecraft] K2 - Paddle & computer co-exsiatence

[TL_Netvision]

> Hello all
> I have my paddle & a computer interface for keying CW connected as per the 
> manual (incl 2 diodes, cathodes at the key-line, anodes at dit & dah 
> terminals).
> The interface is a simple switch (opto coupler 4N37) driven by DTR (RTS is 
> in use by KIO2).
>
> The problem is that I can't get proper keying from the computer unless the 
> K2 is put in "Inp=Hand" mode.
> Doing that the paddle is useless(only one paddle is active).
> Setting back to padln - the paddle works great but than keying from the 
> computer is as if pressing both dit & dah paddles. (Makes perfect sense to 
> me because both diodes are pulled low).
>
> I think the manual says that having an arrangement such as mine is 
> possible because of some auto detecting done by the firmware, but that's 
> not working here.
> Firmware is 2.04p, IO is 1.09.
>
> Any ideas?
> Thanks in advance, Isaac, 4Z4TL, k2 #1574.
