Sleep Inactivity Time—Sets the time that the modem
operates in normal power mode with no activity on the
serial port, parallel port, or telephone line before enter-
ing low-power sleep mode. This feature is disabled if
the timer is set to 0.
0
0–255
seconds
30
Disconnect Activity Timer—Sets the length of time that
the modem stays online before disconnecting with no
activity on the serial port, parallel port, or telephone
line (Ring, hookswitch flash, or caller ID). This feature
is disabled if set to 0.
0
0–255
minutes
38
Hang Up Delay Time—Maximum delay between
receipt of ATH0 command and hang up. If time out
occurs before all data can be sent, the NO CARRIER
(3) result code is sent (operates in V.42 mode only).
“OK” response is sent if all data is transmitted before
timeout. S38 = 255 disables timeout and modem dis-
connects only if data is successfully sent or carrier is
lost.

Data Pattern—Data pattern generated during &T4 and
&T5 transmit tests.
0 = All spaces (0s)
1 = All marks (1s)
2 = Random data

V.34 symbol rate - Symbol rate for V.34 when using the
&T4 and &T5 commands.
