The “M” tells the 232MSS2 it is the set timer mode command and
the “1” indicates to set up up the timer to ignore switching
commands. When the timer is configured in this mode, the
232MSS2 will not accept any switching commands (“A”, ”B”, ”C”,
”D”, or “EOT”) for the specified timer value. After the timer has
expired, the slave port that is connected to the master port will be
disconnected. This feature is useful to prevent inadvertent switching
during binary/graphic type file transfers. For example (smart switch
mode), the timer is configured to ignore switching commands for 5
seconds. The select Port D command is sent to the 232MSS2. Once
Port D is connected a file of unknown data type (so file may or may
not contain a switching command sequence) is to be transferred
through the 232MSS2. For a period of 5 seconds after Port D is
connected, no switching commands will be accepted. As long as the
file transfer takes less than 5 seconds, there is no chance the
232MSS2 will inadvertently switch ports.
