5.3.2.3 Address Delimiter

This is the forward slash character: / (ASCII code 47)

5.3.2.4 Instruction Code

This three-character alphabetic sequence is intended to be a mnemonic of its operational function. This aids in the readability of the
message, should you display it in its raw ASCII form. For example, "GAC" means "Global Amplifier Configuration"; "IPA" means "IP
Address", etc. Both upper case and lower case alphabetic characters may be used (A-Z and a-z, ASCII codes 65-90 and 97-122).

5.3.2.5 Instruction Code Qualifier

This single character further qualifies the preceding instruction code. Instruction Code Qualifiers obey specific rules.

5.3.2.6 Controller-to-Target Rules

From Controller-to-Target, the permitted qualifiers are = or ? (ASCII codes 61 or 63):
= (ASCII code 61)
The "=" qualifier is the Assignment Operator (AO). It means that the parameter defined by the preceding byte should be set to the
value of the argument(s) that follow it. For example: MUT=1 means "set the Mute function to Enabled".
? (ASCII code 63)
The "?" qualifier is the Query Operator (QO). It means that the Target should return the value of the parameter(s) defined by the
preceding byte. For example: SWR? means "return the firmwares installed in the Active and Standby images".

5.3.2.7 Target-to-Controller Rules

From Target-to-Controller, the symbol =, ?, !, *, or # (ASCII codes 61, 63, 33, 42, or 35) is transmitted by the Target device to the
Controller:
= (ASCII code 61)
"=" displays in two ways:
