Ports configuration
You are able to set port settings under RS232/RS485 Port page. There are 3 configurable ports:
/dev/ttyS0, /dev/ttyACM0 and /dev/ttyS1 or /dev/ttyUSB0 (depending on modem version).
Every port can be set to different mode. On /dev/ttyS0 you can set terminal, ModBus gateway or
NTRIP mode. Two other ports can work as modem port (modem control and modem data) or SMS
receiving port (see also: SMS Actions section).
Every port can also be set to forwarding mode that allows user to forward it to TCP/UDP port (as
server or client). Port /dev/ttyS0 can also be forwarded to modem control or modem data port-in
that case no other mode can be set on that port.
Setting certain modes on /dev/ttyS0 and /dev/ttyS1 (LTE modem variant only) enables setting port
parameters: baud rate, data bits, parity checking and protocol. If parameter is inactive that means
that user can't control it in currently set mode.
