4.2 Service Mode
4.2.1 Virtual COM Mode
In Virtual COM Mode, the driver establishes a transparent connection between a host and the serial device by
mapping the port of the serial server serial port to a local COM port on the host computer. Virtual COM Mode
supports up to five simultaneous connections, so that multiple hosts can send or receive data by the same serial
device at the same time.

defined time interval (Alive Check) to remote host to check the status
of TCP connections. If the TCP connection is not alive, the
connection will be closed and the port will be freed.
