Comport Transaction Functions
Prototype: u32 S26_ComSetMode(u32 hbd,u8 dev,u16 cdiv,u8 mode,u8 leds,u32 msec,u32 retries);
Parameter Type Description
hbd u32 MM handle.
dev u8 Logical device identifier for the target comport. Specify a value from 1 to 4 to
address comport 1 to 4, respectively.
cdiv u16 Clock divisor for the baud rate generator. May be set to any value between
SIO_BR_300
and SIO_BR_115200.
mode u8 Collection of enumerated values that set various operating attributes. The byte value
is formed by logically or’ing one value from each of the following groups:
Parity: SIO_PARITY_ODD, SIO_PARITY_EVEN, or SIO_PARITY_NONE.
Databits: from SIO_DATABITS_5 to SIO_DATABITS_8.
Stopbits: SIO_STOPBITS_1 or SIO_STOPBITS_2.
Flow control: SIO_FLOWCTRL_OFF or SIO_FLOWCTRL_ON.
Interface type: SIO_PHY_RS232, SIO_PHY_RS422_IDLEON,
SIO_PHY_RS485
or SIO_PHY_RS422_IDLEOFF.
leds u8 Specifies the events that will cause the comport status LED to light. May be any
combination of the following: SIO_LED_TRANSMIT, SIO_LED_RECEIVE,
SIO_LED_ERROR
. The byte value is formed by logically or’ing the desired events.
msec u32 Maximum time, in milliseconds, to wait for the MM to respond.
retries u32 Maximum number of transaction retry attempts.
cdiv may be set to any of the following values in order to
program standard baud rates. Bold type indicates the default
setting after a module reset. Setting cdiv to any value not
shown in the table will result in a non-standard baud rate.
The mode byte is shown below. Bold type indicates the
default settings after a module reset.
