another feature for cwdaemon

[Sergei Klink <sklink@yandex.ru>]

Hi all,

I saw somebody use a keyer interface with TRlog which has a connector for the 
manipulator itself, to make a "software" automatic key(pins 12 and 13 on the 
parallel port), and decided to try to do something similar with 
cwdaemon(0.5). The I/O port programming HOWTO seems to be pretty clear(I 
happened to have a 1998 book lying at my feet at the moment), although some 
of the things I just cannot understand there(why did I have to use != instead 
of == ?). Besides, I'm a very poor C programmer(and not even really a HAM 
yet), so maybe this is more of a suggestion than solution(also, I don't know 
if anyone used something similar for the serial port, so I just made a dummy 
function to prevent it from segfaulting); although it seems to work somehow.

Anyways, (please excuse me if this is the wrong place to send it) the patch 
for cwdaemon-0.5 is attached, just to show what I meant(I'm not exactly sure 
how to do this with 0.6beta1).
