2. Input/Output port
This port can be configured as either an input one or an output one.
To configure it as an input port, first issue AT+WIOW=2, 0 to disable the output port.
Use AT+WIOR=3 to read the status of this input port. Response +WIOR: 0 represent
Logic HIGH (>3V); Response +WIOR: 1 represent Logic LOW (<0.5). To use it as an
output port, issue AT+WIOW=2,1 will turn it on and it will drain current to ground. The
current is recommended not to exceed 5mA. Issue AT+WIOW=2,0 will turn it off.
3. RS232 Auto-online mode (power saving)
When being in the auto-online, the RS232 transceiver will shut down most of its
hardware to save power is it does not detect a valid input for more than 100uS. The
RS232 transceiver will wake up when valid input is detected again.
By default, the RS232 transceiver is put in auto-online. This mode can be turned off by
issuing AT+WIOM=,16.
