Firmware
Sub-menu: /port firmware
This submenu allows to specify directory where drivers for 3g modems can be uploaded and used.
Remote Access
Sub-menu: /port remote-access
If you want to access serial device that can only talk to COM ports and is located somewhere else behind router, then
you can use remote-access.
As defined in RFC 2217 RouterOS can transfer data from/to a serial device over TCP connection.
Enabling remote access on RouterOS is very easy:
/port remote-access add port=serial0 protocol=rfc2217 tcp-port=9999
Note: By default serial0 is used by serial-terminal. Without releasing the port, it cannot be used by
remote-access or other services
