This mode is only supported if there is at least a one-bit delay between characters received by the SDM-SIO1A.

6.3.1.2 SerialClose()

This will place the SDM-SIO1A unit into shutdown mode where only SDM communications will
operate. This means any data coming into the SDM-SIO1A on the RS-232/RS-485 interface will
be lost.
This is the lowest possible power mode, and for optimum power efficiency, the SDM-SIO1A
should be placed in this mode whenever possible.

6.3.1.3 SerialIn()

The primary difference when using this instruction with an SDM-SIO1A compared to when it is
used with a serial port built into the data logger is timing. If the data has already been sent by the
remote sensor/system, the instruction will run in a few tens of microseconds as the data is read
