Virtual COM Port
Virtual COM Port mode (also called COM port redirection) allows you to
map a COM port on your PC to the serial port on your ESR901WB. Using
the RealPort software (included with the ESR901WB) you create virtual
COM ports on your PC. When your application sends data to this port,
RealPort redirects the data across the network to serial device connected to
the ESR901WB serial port. The network is transparent to the user application
and the serial device connected to the ESR901WB.
Paired Mode
Paired Mode (also called Serial Tunneling or Serial Bridge mode) allows
serial devices connected to two ESR901WB serial servers to communicate
across a network. The two ESR901WB serial servers automatically connect
to each other.
In Paired Mode the heartbeat feature ensures reliable communications by
restoring the connection if communications are temporarily lost at either end
due to loss of power or Ethernet connection.
Other Communications Modes
ESR901WB Wireless Serial Servers also feature the following
communications profiles:
Modem Emulation Mode allows you to configure the serial port to operate
as if it is a modem. For legacy applications where a serial device is set up to
communicate through a modem, the serial device can now be connected to
the ESR901WB and communication occurs over the network. The
ESR901WB emulates modem responses to and from the serial device.
In Console Management Mode the ESR901WB can be configured for
connection to the management port typically found on network devices such
as routers, switches and servers. This allows remote management of the
network device. Communication can be accomplished using telnet to a
specific port in the serial server.
Custom Mode allows you to custom configure the ESR901WB serial port
and is used if your application does not fit into any other predefined modes.
