This command switches multiplex mode on and off. In multiplex mode, the R/W
heads are controlled according to the time multiplex process, i.e. only one R/W
head is active. The procedure minimizes mutual interference between R/W
heads, allowing two R/W heads to be mounted side by side.
Each IDENT channel sends a response in reply to an MM command.
Multiplex mode
If a R/W head is not connected to a channel, the response telegram receives the
status "06h" (hardware fault) from this channel.
