serparams — Array of structure serialparam that con-
tains values that the UART device is to
be initialized with. The valid serparams
values below describe the structure
members.
serparams baud 2400/9600/19200/38400/
57600/115200 Sets the baud rate to any of the default
values.
serparams data bits 7/8 Sets the data bits to any of the default
values.
serparams stop bits 1/2 Sets the stop bits to any of the default
values.
serparams parity PAREVEN/ PARODD/

PARNONE
Sets the parity to any of the default val-
ues.
serparams settings Can contain combinational values with logical OR (|) operation, as
described below:
SERSET_DTR_ON This Flag directs the serial driver to
assert the data terminal ready (DTR)
signal when the corresponding serial
device (UART) is open.
SERSET_RTSCTS This Flag directs the UART driver to use
the ready to send (RTS)/clear to send
(CTS) flow control over the serial link.
SERSET_DTRDSR This Flag is currently not used by the
UART driver.
SERSET_XONXOFF This Flag is currently not used by the
UART driver.
SERSET_ONLCR This Flag directs UART driver to convert
each outgoing new-line character (for
example, \n) to a new line + carriage
return (for example, \r\n). This setting
is required by some terminal emulators
to ensure that the console output is dis-
played correctly. This Flag must not be
used with PPP.
