6.3 ISSPA Telnet Interface
The CPA provides a Telnet
interface for the purpose of
Equipment M&C via the
standard equipment Remote
Control protocol. The Telnet
interface requires user login
at the Administrator level
and Read/Write level. An
example of the login process
is shown here:
Once logged into the Telnet interface as Administrator, you can access the standard remote
control interface defined in Chapter 7. SERIAL-BASED REMOTE PRODUCT MANAGEMENT.
6.3.1 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  Properties 
Settings  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.
An example of login and remote
command/query execution, when using
HyperTerminal as the interface, is shown
here:
