[1000mp] Fw: CW Interfacing query

[Mike Gilmer, N2MG]

There are so many problems with using the serial ports (lousy
standardization), that I opted for the parallel connection for CW sending.
Also, this frees up the serial ports for other duty (TNC/rig control, etc.).

Are you using a stereo phone jack?  Did you use the circuit in the TR manual
(any substitutions) with the correct pinouts from Table 26?
