7.4.1.1 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.
In order to view the full response messages, you may use the HyperTerminal terminal
emulation program configured as a Telnet client. Configure HyperTerminal as follows:
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-625A’s
Traffic/Management IP
Address as the Host Address
(e.g., 192.168.1.1).
B. Enter TCP Port 23 as the Port
number.
C. Set Connect using to TCP/IP
(Winsock) instead of COM1 or
COM2.
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 Receiving
section.
Examples of login and remote command/query execution, when using HyperTerminal as the
interface, appear as follows:
