3.4.5 Power-up Message
The normal power-up text is shown below. ASCII control characters
are shown in boldface:
CR is 0x0A, LF is 0x0D, and BEL is 0x07.
CR LF ENI Monitor on, type HEL <CR> for help.
CR LF Power-Up Delay in effect for next 15 seconds.
CR LF BEL *
If the power-up delay was caused by a watchdog reset (or from the
WAT command), the text above will be
preceded by the message:
CR LF [WATCHDOG RESET]
After 15 seconds have elapsed, the generator sends the following text.
The asterisk enclosed by curly braces is a unique string that the
generator sends
only on power-up. A host computer can use this
string to detect and verify power-up of the generator.
CR LF Power-Up Delay Complete.
CR LF BEL {*}
The messages described in this section are the only cases where the
generator sends unsolicited characters to the terminal.
3.4.6 Backspace Characters
Backspace or delete characters (0x08 or 0x7F) allow limited editing.
When one of these characters is received, the last character in the line
buffer is deleted and the following three characters are returned. (
BS
is the backspace char, 0x08, and SP is the space char, 0x20.)
BS SP BS
This ensures that a terminal screen backspaces its cursor and
removes the last character.
3.4.7 Escape from Indefinite Loops
Some commands continue indefinitely. The escape character is used
to exit from this condition. Upon receipt of the escape character, the
controller will terminate the loop and respond with the standard
command completion string,
CR LF *.
