FCD-E1 Using the Explicit Command Mode 4-15
4.5 Using the Explicit Command Mode
This section presents the supervision language syntax, usage and set of commands
used in the explicit mode.
Explicit Mode Command Syntax
• Commands can only be entered when the FCD-E1 supervisory port prompt is
displayed. The prompt is FCD>, and it always appears at the beginning of a
new line. The cursor appears to the right of the prompt (except when using a
multidrop configuration).
• Commands are case-insensitive, e.g., you can type commands in either lower
case and/or upper case letters and they will be interpreted as upper case only.
Logical names entered in the user-defined section of the prompt can however
use lowercase and uppercase letters, as entered by the user.
• To correct typing errors, backspace by pressing the BACKSPACE key until the
error is cleared, and then type the correct characters.
• To clear the whole command string before its entry is completed, press
CTRL+C (that is, hold the CTRL key down and type C). This will result in the
display of the FCD-E1 prompt, and a new command can be entered.
• Use space as a separator between command fields and/or parameters.
• Leading zeroes may be omitted.
• Commands must end with pressing the <Enter> key.
• To obtain help, type H.
• Commands addressed to one of the FCD-E1 ports include a port identifier:
 The main link port has the identifier ML.
 The sublink port has the identifier SL.
 The data channel or Ethernet port has the identifier HS.
