[BC] AP 10 Bells Survery

[Darryl Parker]

In ASCII X3.4 BEL is "0000111", so ten bells would be "0000111 0000111 0000111 0000111 0000111 0000111 0000111 0000111 0000111 0000111".

Does anyone here know the specifics of the Extel data protocol -- in
other words, does it want to see Baudot,  7-bit ASCII, or what?

There's an abandoned Extel sitting on the shelf at one of my client
stations... so I'm thinking of asking to take it off their hands and
building a interface circuit to print RTTY.

The same station also has a classic old Type 15 in the closet...
tempting, but ya gotta draw the line somewhere.  If anyone is
interested in that, let me know your offer.  You'll pay the freight,
of course.
