You can recall just the last command with the cursor positioned on the command line. This is done with two slashes:

NM> //

---Commands---

ck

The number of lines backward from the last line can be specified with the corresponding number of slashes after the command stack command (that is, the first slash). For example, to display the stack with the cursor positioned on the second to the last line, enter three slashes.

A slash followed by a number can be entered. In this case, only the latest command entries are displayed starting with the command corresponding to the line number specified (counting backward from the last line). The cursor is positioned on the line specified.

Whenever the cursor is positioned at a command line, either by slashes or a number, that line may be edited. Pressing the carriage return key will enter the command. If you do not wish to enter this line, you can enter a slash to repeat the whole command stack, or move the cursor to a blank line (and press the return key) to return to the NM> prompt.

The NM command stack is not saved between NM sessions.

Error Messages

Command Entry

If an illegal or unrecognized Node Manager command is entered, the User Interface modules (NM, NM2) return command entry errors. Errors found are returned in sequential order (there may be errors not found). An up"arrow cursor mark or circumflex is displayed at the position of an error with an explanation of the problem.

NM> RC,0P-00-09-00-02-0B,0A<RETURN>

 

^1

error

1

---> Address must be XX-XX-XX-XX-XX-XX, where X is a hex digit

error

2

---> PAR# must be an integer in the range 1 to 11 or ’A’

NM>

These are typical command entry error messages (for reference, see the Read Link Configuration command, RC, described later in this manual). In error 1, the Station Address contains an improper hexadecimal digit. In error 2, a hexadecimal number instead of a decimal value has been entered. The Node Manager software points out the source of the problem and provides a short description of how to correct it. The command must then be reentered.
