To connect the external additives,
Loading arms running on Arm board 1 of MSC-L can use COM1 or
COM2 ports. External additive streams 1-12 are on Arm Board 1.
Loading arms running on Arm board 2 of MSC-L can use COM6 or
COM7 ports. External additive streams 13-24 are on Arm board 2
The communication uses FMC Smith protocol that needs to be
configured on the COM ports of both devices.
