Re: CW interface capabilities

Hi Dee,

I've had lots of good reports from users who have constructed the serial port interface on my website.  I believe the serial schematic is fine.

If anyone has built a parallel interface and has a copy of the schematic that they used I'd love to add it to the website.

I am talking about the serial port.  Which pins on which component are
backwards in the diagram?  I assembled the serial interface per the diagram
on the n3fjp website.
