AA (range 00-FF) represents the 2-character hexadecimal
address of an analog input module.
VV are two hexadecimal values. The values are interpreted by
the module as two binary words (4-bit). The first word repre-
sents the status of channel 4-7, the second word represents the
status of channel 0-3. Value 0 means the channel is disabled,
value 1 means the channel is enabled.
(cr) is the terminating character, carriage return (0Dh).
Example command: $026(cr)
response: !02FF(cr)
The command asks the analog input module at address 02 to
send the status of it input channels. The analog input module
at address 02 responds that all its multiplex channels are
enabled (FF equals 1111 and 1111).
