Instruction Code Qualifier

This is a single character which further qualifies the preceding instruction code.
Code Qualifiers obey the following rules:
They have these meanings:
The '=' code (controller to target) is used as the assignment operator, and is used to
indicate that the parameter defined by the preceding instruction code should be set to the
value of the argument(s) which follow it.
For example, in a message from controller to target, UFQ=13750.0 would mean 'set
the transmit frequency to 13750 MHz'
The '?' code (controller to target) is used as the query operator, and is used to indicate
that the target should return the current value of the parameter defined by the preceding
instruction code.
For example, in a message from controller to target, UFQ? would mean 'return the
current value of the uplink frequency'
1. From Controller to Target, the only permitted values are:
= (ASCII code 61)
? (ASCII code 63)
2. From Target to Controller, the only permitted values are:
= (ASCII code 61)
? (ASCII code 63)
! (ASCII code 33)
* (ASCII code 42)
