Serial Addressability
This example shows that it is possible to communicate to specific serial
devices (
e.g.,
PC 2 COM1, and PC 3 COM1) over the radio network.
Note that TCP is used as the transport layer for communication here,
which provides data reliability at the application level.
1. Configure Remote 1 and Remote 2 by navigating to the
Term Srvr 2
COM2 Configuration
screen and setting the parameters as listed below.
(Note that an Ethernet connection to Remote 1 and Remote 2—not
shown in Figure 28— will be required for this step, unless Telnet is
used.)
Status: Enabled
Mode: TCP Server Socket
Local Radio Port: 30000
Connection Timeout: 0 Seconds
Persistent Connection: Yes
2. Navigate to the
COM2 Port Settings
of Remote 1 and Remote 2 and
configure them as listed below (note that VRCs are not used):
Mode: RS232
Baud Rate: 115200 bps
Format: 8 char bits, no parity, 1 stop bit
Buffer: Data Handling ON
Device: DCE
Talk on: VRC-1
Listen to: VRC-1
3. Click
Commit Configuration
after the changes are made.
To test the functionality of the Terminal Server, open a HyperTerminal
session on PC1 and connect to the Remote Terminal Server as shown in
Figure 29.
