Configuring the Terminal Server
42 Terminal Server User Guide
COMredirect
The COMredirect utility acts as a com port redirector that allows applications to talk to serial
devices across a network as though the serial devices were directly attached to the server. You
can map the baud rate of the host COM port to a higher baud rate for the serial line that connects
the serial device and the Terminal Server. You must be running the COMredirect daemon on the
host that is accessing the serial device for this to work. See
COMredirect on page 123 for more
information about the COMredirect utility.
Hardware Configuration
Configure the ethernet interface that is connecting the Terminal Server to the LAN and the serial
cable that is connecting the Terminal Server to the serial device.
Ethernet Connection
You need to know the ethernet interface speed and duplex as follows, unless you are using the
Auto detect option:
z
10 Mbps half or full duplex
z
100 Mbps half or full duplex
Serial Connection
You also need to know the serial interface specifications as follows:
z
EIA-232 and its speed
z EIA-422 and its speed
z EIA-485 and
– its speed
– half duplex with/without echo suppression or full duplex
– TX driver control is automatic or RTS
Other
The most important thing to keep in mind when configuring the hardware parameters is to make
sure that they are consistent with the serial device you have connected to the port. So, if you are
connecting to a modem that sends out a DSR signal, you probably want to turn the
Monitor DSR
option on. Following is a list of just some of the other hardware configuration options:
z
Data Bits—5 to 8
z
Stop Bits—1, 1.5, 2
z
Monitor DSR—on, off
z Monitor DCD—on, off
z Parity—None, Odd, Even, Space, Mark
z
Flow—Software, Hardware, or None
