F(6) A(0): Read Module Number
281 Decimal, 119 Hex
F(7) A(0): No-op Read
No data are returned.
F(9) A(0): Reset Module
Resets all process gates. This command could be dangerous during certain operational scenarios.
Q and X are returned immediately for all valid codes. This module never asserts LAM.
