[Elecraft] Using N1MM to Key a K3 with no outboard keyer

[Don Wilhelm]

Ted,

That is something in N1MM which effectively tell the N1MM software to 
send the ASCII string which follows through the CAT port.

You may find more information in the N1MM help file or forums.

Each command line contains the string CATA1ASC before the command KY.  Without the CATA1ASC, hitting the Fn key does nothing.  With it, and with the standard KY programming command, it works -- on the KX3 at least.  My K3 is at my other QTH so I haven't tried this on that rig yet, but here's my question -- what is the CATA1ASC for?  I did a word search in both the KX3 and the N1MM manuals, and in the KX3 Programmer's Guide, and I could find no mention of the CATA1ASC string.  Had I not found the examples on the Internet accidentally I would still be trying to make this work with no success.
