Activate/deactivate modem hardware features (continued)
• For <type = 7> (Buzzer)
• 0 = BUZZER_EN outputs a PWM signal (Default)
• 1 = BUZZER_EN outputs as a GPO
<uartgroup> (Pin type duplexed for extended UART signals—DCD/DSR/DTR)
• 0 = Extended UART (8-wire) disabled. (4-wire enabled)
• 1 = GPIO
• 2 = PCM
• 3 = SPI
<uartlinedcd> (DCD line)
• 0 = Disabled
• 1 = Enabled
<uartlinedtr> (DTR line)
• 0 = Disabled
• 1 = Enabled
<uartlinedsr> (DSR line)
• 0 = Disabled
• 1 = Enabled
<uartsleep> (UART sleep flag)
• Sleep flag is referenced only if DTR line is disabled.
• 0 = Sleep enabled
• 1 = Sleep disabled
• Behavior summary:
• <uartgroup = 1|2|3> && <uartlinedtr = 1>: UART goes to sleep when DTR is
deasserted and wakes when DTR is asserted.
• <uartgroup = 0> && <uartsleep = 0>: UART goes to sleep 15 seconds after
bootup (if no activity), and after 4 seconds of normal inactivity. UART wakes
when activity is detected on Rx line; the port may be used after short delay
(~1 second).
• <uartgroup = 0> && <uartsleep = 1>: UART never sleeps.
