Hi Dave, (01)
Well, Jake has given me a chord keyset to play with, and I'm trying to
figure out how to interface with it. (02)
My first problem is that I can't tell whether it should be plugged into
a serial port or a parallel port on a PC. (03)
The keyset has a Cannon DA-15S (Cinch) female connector at its end (15
pin, D shape, 8 on top, 7 on bottom, part number "DA51211-1 USA"). (04)
She also gave me a cable which has on one end a DA-15P male connector
which plugs into the keyset's female connector. The cable itself is a
rainbow-colored ribbon made up of six separately wrapped wires (wrapped
light-brown, red, orange, yellow, green, blue). (05)
The other end of the cable is a 25 pin male connector (D shape, 13 on
top, 12 on bottom) with nothing listed except "AMPHENOL-117" on it.
Since it is a 25 pin connector, that means it could either be a parallel
port connector, or a DB25 serial port connector. (06)
It could plug directly into a PC parallel port (which is female), or I
could use a DB25-female to DB9-female converter cable to plug in to a PC
serial port (which is male). (07)
I spent some time looking through your AugTerm assembler code to see if
I could understand how it reads from the keyset. Alas, I could not
determine as yet whether it reads from a parallel or serial port, for
the keyset. (08)
I tried to search the web to find any technical information on the
keyset but also came up empty. It would be great to have the pinout for
the keyset, if anyone has that available. (09)
Do you remember off-hand where the keyset plugs into a machine? (010)
Thanks! (011)
