General Commands, Cont. 5 Asynchronous Operating Commands DTE Controlled Fallback Rate (Pin 23) *FB Pin 23 of the EIA-232 DTE connector provides a signal input to the modem for DTE fallback. If the modem is not using DTE fallback, set this option to ignore pin 23. To cause the modem to act on high / low levels of pin 23, enable this option. Negative level forces a higher rate for primary data rate; positive forces a lower rate providing a fallback rate.
