And remember, an AT keyboard is nowhere near 1200 baud. And the AT keyboard not only tells you when a key is pressed, it also tells you when it is released. It's starting to sound like the 9100 keyboard just sends simple text as it's typed. If that is what it is REALLY doing this should be very simple. (Uh, what are we trying to do again?) Kev wrote:
Browsing thru the 9100 service manual.
The 9100 Keyboard is TTL level Serial ASCII @ 1200 BAUD
1 Start Bit 8 Data Bits (LSB->MSB) 2 STOP BITS (AT Keyboards do 1/8/1parity/1stop)
RESET is sent from the CPU to the Keyboard.
Does a RESET cause a keyboard response?
Thanks, Kev
