4. Serial Port Configuration
4.1. Overview
The serial port configuration capability allows the user to configure the host mode of each port, serial
communication parameters, cryptography, port logging parameters and other related parameters.
The serial port’s host mode can be set as any of the following:
 TCP :
The STS Series operates as a TCP server and client. If the connection is not established, it accepts all
incoming connections from any registered remote hosts and connects to the registered remote hosts if
there is any data from the serial devices. Otherwise, it will send data back and forth. In summary, the
STS Series will work as if it is virtually connected to the remote host.
 UDP :
The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.
 Modem emulation :
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.
 Virtual COM :
This feature will be added later.
With the port-logging feature while in console server mode, the data sent through the serial port is
transferred to MEMORY, SYSLOG server, NFS server’s storage or an ATA/IDE fixed disk card
using a PC Card slot. The user can also define keywords for each serial port that will trigger an email
or SNMP trap notification. This will enable the user to monitor the data from the attached device.
Using MEMORY to store data will result in loss of all information when the STS Series is turned off.
Use the NFS server or ATA/IDE fixed disk card to preserve the serial port log data.
The serial ports can be configured individually or all at once. Table 4-1 summarizes the configuration
parameters related to the serial port configuration.
