Hardware Interface
4.3 Serial Modem Interface
iChip CO661AL-S includes a dedicated port to interface a serial modem. The modem
interface is a serial DCE interface. Speeds of 2400, 4800, 9600, 19200, 38400, 57600,
115200 and 230400 bps are supported in the following data format:

Table 4-2 Host Data Format
Actual baud rate may be preprogrammed or dynamically defined as equal to the auto
baud rate detected on the serial host interface (when CO661AL-S operates in Serial
mode). When the CO661AL-S operates in Parallel mode, the modem interface baud rate
must be preprogrammed.
All serial modem input signals (RXDM, -DSRM, -CTSM, -CDM) are 5V tolerant.
iChip does not provide a Ring Indicator input signal.
