Full modem handshaking is supported by the AC4490 when enabled in EEPROM. Modem mode is incompatible with
RS-485 DE. The line states are updated a maximum of once per 20 ms and only change when toggled by the
appropriate line on the remote radio. Because Command/Data performs an alternate function when modem mode is
enabled, on-the-fly CC Commands cannot be used and Configuration Mode is entered by forcing 9600 baud through
the 9600_Baud pin (pin 12). Therefore, modem mode is disabled when the radio is forced to 9600 baud. Both
modem interfaces are shown in the tables below.
