Telnet Interface
The LBC‐4000 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 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.
