CHAPTER 9: Out-of-Band Initialization Strings
114 WatchGuard Firebox System 6.0
7 Expect “OK” back.
8 Send “ATS0=1” to direct the modem to answer incoming calls after
one ring.
9 Expect back a final “OK” from the modem.
For an out-of-band management connection, the modem needs to be set up to
answer the phone when it rings, and to use hardware flow control on the serial line.
The Flow Control and Modem Initialization fields on the OOB tab enable you to
make these settings.
Common initialization string values
Auto-answer
Send the string
ATS0= x, where x = the number of rings before
answering. For a pickup after one ring, enter
ATS0=1 .
Special sequences
TIMEOUT value
The initial timeout value is 45 seconds. Once changed, the timeout
setting remains in effect until it is changed again.
EOT
The special reply string of EOT indicates that the chat program
should send an EOT character to the remote. This is normally the
end-of-file character sequence. A return character is not sent
following the EOT. The EOT sequence can be embedded into the
send string using the sequence Ctrl+D.
BREAK
The special reply string of BREAK will cause a break condition to
be sent. The break is a special signal on the transmitter. The break
sequence can be embedded into the send string using the \K
sequence.
Escape sequences
The expect and reply strings may contain escape sequences. All of the
sequences are legal in the reply string. Many are legal in the expect
sequence. Those that are not valid in the expect sequence are so indicated.
