ADVField/Hydra Operation Manual (September 1, 2001) 9
• BREAK - A serial communication signal that causes a reset in the ADVField electronics and
returns the system to command mode. A
BREAK requires holding the transmit serial communi-
cation lines high for a period of at least 300 ms. A
BREAK can be sent from the software pro-
gram,
SONTERM , by pressing ALT+B . or by sending three + characters in succession (i.e., +++ ).
See the ADVField Software Manual for details.
Note
: The 300-ms break period is longer than that used by most standard terminals. If you
use a terminal emulator other than
SONTERM , and are have difficulty waking the sys-
tem, either reconfigure your emulator for a longer break period or use
SONTERM .
