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-625A's

Traffic/Management IP

Address as the Host Address

(e.g., 192.168.1.1).

b) Enter TCP Port 23 as the Port

c) Set Connect using to TCP/IP

(Winsock) instead of COM1 or

2. For ASCII Setup (File  Properties  Settings  ASCII Setup), as shown above at the far

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

Examples of login and remote command/query execution, when using HyperTerminal as the

interface, appear as follows:
