"a" Select and Play a Sound:
This command is used when you just want to play any sound recorded in
the AB-Clock. Valid entries are from 1 to 98 to select specific spiels, or 99 to
hear whatever spiel is next in line.
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
"b" Baud Rate:
The serial port on each AB-Clock can support any of the following baud
rates:
¥ 110
¥ 150
¥ 300
¥ 600
¥ 1200
¥ 2400
¥ 4800
¥ 9600 (default value)
¥ 19,200
¥ 48,000
¥ 96,000
The lower baud rates will require that the dead man circuit be discon-
nected (U-7 pin #6) while in configuration mode. The reason for this is that
the dead man needs to be updated about once a second. At the lowest
baud rates it will be spending so much time printing that it will time out and
reset the system. 9600 baud is an average speed to run the system.
The default speed is 9600 baud. This command doesn't take effect until
you enter the eXit command.

"c" Odd Parity Toggle:
This toggle enables the ODD PARITY data check on the serial port on the
AB-Clock. Parity is a method of confirming that the data sent to the audio
system arrives intact. Any data that gets jumbled is ignored. If ODD PARITY is
enabled, it must be enabled on your computer or terminal. The default
value for this command is OFF. This command doesn't take effect until you
enter the eXit command. It is not normally used.

"d" Eprom Type:
The following types of Eproms are currently supported by the AB-Clocks:
¥ 27C512
¥ 27C010
¥ 27C020
¥ 27C040 (default setting)
¥ 27C080
All the Eproms on an AB-Clock must be of the same type. This command
doesn't take effect until the eXit command is completed.

"e" Input Debounce:
This sets the number of times the firmware inside the AB-Clock will check
an input before it believes that it is valid. A typical value is 10 or so. If you
are operating in a particularly noisy electrical environment, you may need
to raise this to prevent false triggering.
