[1000mp] LPT CW Interface

[Joe Subich, W4TV]

Alex, 

While I have a prejudice in favor of microHAM products, 
there are other interfaces (check www.hosenose.com, K1NU, 
and others) that will provide rig control, CE (using the 
DTR line) and PTT (using the RTS line) from a serial 
port.  It is not necessary to tie up your parallel port 
in addition to a serial port.  Most current software will 
support CW and PTT on the serial port in addition to rig 
control.  

Doing CW by "flipping" the DTR is difficult and often 
results in less than optimal ("broken") CW if Windows 
is off "doing something else" when the CW sending routine 
needs to change the state of the CW line.  

73,
