Notes:
Query for the number of channels on an IO device, responds with IOCHANNELCOUNT
Query for direction of the I/O channel, where <io-chan> is the integer channel number,
responds with IOCHANNELDIRECTION
Query for input sense of the I/O channel, where <io-chan> is the integer channel num-
ber, responds with IOCHANNELINPUTSENSE
Query for state of the I/O channel, where <io-chan> is the integer channel number,
responds with IOCHANNELSTATE
Sets the I/O channel direction, where <io-chan> is the integer channel number and <io-
dir> is INPUT or OUTPUT
Sets the I/O channel input sense, where <io-chan> is the integer channel number and
<io-sense> is HIGH or LOW
Sets the I/O channel state, where <io-chan> is the integer channel number and <io-
state> is ON or OFF
Notes:
Response to ?IOCHANNELCOUNT, where <count> is an integer value
Response to ?IOCHANNELDIRECTION, where <io-chan> is the integer channel num-
ber and <io-dir> is INPUT or OUTPUT
Response to ?IOCHANNELINPUTSENSE, where <io-chan> is the integer channel
number and <io-sense> is HIGH or LOW
Response to ?IOCHANNELSTATE, where <io-chan> is the integer channel number
and <io-state> is ON or OFF
