12.4. Controlling Connections using PIO5 and PIO6
PIO5 can be used to control the TCP connection. Once configured with the set system IO command the
module will attempt to make a connection to the stored IP and PORT address when set high and will
disconnect when set low.
set sys io 0x20 (configures PIO5 to connect/disconnect )
You can monitor the connection status by reading PIO6. High indicates an open connection, low indicates
no connection. Use the command set system IO to enable PIO6.
