6.5.1 Telnet Operation via HyperTerminal
There is a disadvantage when using Windows Command-line as a Telnet client. 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, Comtech EF Data recommends use of the
HyperTerminal terminal emulation program, configured as a Telnet client.
Configure HyperTerminal as follows:
1. Ensure that the connection is made
using TCP/IP (Winsock) instead
of COM1 or COM2, as shown at
the near right.
2. ASCII Setup (File Æ Properties Æ
Settings Æ ASCII Setup): Check
the "Send line ends with line
feeds" option in the ASCII Sending
section, and the "Append line
feeds to incoming line ends"
option in the ASCII Receiving
section, as shown at the far right.
Examples of login and remote command/query execution, when using HyperTerminal as the
interface, appear as follows:
