Port Enable/Disable
Each serial port can be enabled or disabled. If a serial port is disabled, users cannot access the serial port.
Figure 21

Host Mode Configuration
The Model 2285 operating mode is called the “host mode.” Three host modes are available:
•
TCP mode
: The Model 2285 works as both TCP server and client. This mode works for most applications,
since it will transfer the data either from serial port or from TCP port. If there is no connection established
on a TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the
transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the regis-
tered remote hosts and redirects the data.
•
UDP mode
: The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol
•
Modem emulation mode
:
Select this mode when the serial device already supports modem AT commands
or users want to perform the session control by using AT commands. Only TCP session is supported.
