Modem Escape Sequence
Enter the ASCII escape string to be sent to the modem before sending a command string. This
string can be up to five characters long and is typically set to +++. If this field is left empty, the
BMC uses +++. The modem escape sequence is not sent to the modem if DTR Hang-up is
enabled on the initial Serial/Modem Channel Configuration Sub-task screen.
Hang-up Sequence
Enter the ASCII string that is sent to the modem to terminate the session. This string can be up to
eight characters long is typically set to ATH. The BMC automatically follows this string with an
<Enter> character when sending it to the modem. If this field is left empty, the BMC uses ATH.
The hang-up sequence is not sent to the modem if DTR Hang-up is enabled on the initial
Serial/Modem Channel Configuration Sub-task screen.
Dial Command
Enter the ASCII string for the modem string used to initiate a dial sequence with the modem. If this
parameter is left empty, the BMC uses ATD.
Ring Duration
The Modem Ring Time setting specifies the time it takes the BMC to claim the serial connection
after detecting the phone ringing while monitoring the Ring Indicator (RI) line. By configuring the
Ring Duration, you can specify the amount of time that the BMC takes to switch the mux when RI
is first detected.
The ring duration value should be entered in 500 ms increments and the SMU will round entries
down to the nearest 500 ms. A value of 0 configures the BMC to switch the mux immediately on
the first detected transition of RI.
Enter a value between 0 and 31509; be aware that the SMU rounds values down to the nearest
500 ms, so the maximum valued used is 31500.
Ring Dead Time
This setting allows you to specify the amount of time that the RI signal must be deasserted before
the BMC determines that ringing has stopped.
The ring duration value should be entered in 500 ms increments and the SMU will round entries
down to the nearest 500 ms. A value of 0 configures the BMC to switch the mux immediately on
the first detected transition of RI. The value entered should reflect any dependencies on modem
type, location of server, and the phone line carrier.
Enter a value between 0 and 7999; be aware that the SMU rounds values down to the nearest
500 ms, so the maximum valued used is 7500.
