Using HyperTerminal for Telnet Remote Control Operation
There is a disadvantage when using Windows Command-line as a Telnet client with the serial-
based Remote Control protocol. Since Command-line cannot translate a '\r' (i.e., carriage return
or "CR") to a '\r\n' (i.e., CR+line feed "LF") for the messages coming from Telnet Server, any
multi-line Target-to-Controller response (e.g., the response to the FRW? query) will be displayed
as one line, with the latter lines overwriting the previous lines.
You may use the HyperTerminal terminal emulation program, configured as a Telnet client, to
view the full response messages. Do these steps to configure HyperTerminal:
1. Be sure to properly define the "Connect To" Telnet connection properties (File
Properties), as shown below at the near right:
a. Enter the CDM-425's
b. Enter TCP Port 23 as
c. Set Connect using to
2. For ASCII Setup (File Properties Settings ASCII Setup), as shown above at the
far right:
a. Check the "Send line ends with line feeds" option in the ASCII Sending section.
b. Check the "Append line feeds to incoming line ends" option in the ASCII
Examples of login and remote command/query execution, when using HyperTerminal as the
interface, appear as follows:
Ethernet-based Remote Product Management
Traffic/Management
IP Address as the
Host Address (e.g.,
192.168.1.1).
the Port number.
TCP/IP (Winsock)
instead of COM1 or
COM2.
