// Some commands may check [4] for the terminator. Others may check [3]. Typically, older
// MCMAN revisions will exclusively check [4], and newer revisions will check both [3] and [4]
// for different values. In all cases, they expect to see a valid terminator value.

// Also worth noting old revisions of MCMAN will not set anything other than 0x55 for the terminator,
// while newer revisions will set the terminator to another value (most commonly 0x5a).
