com2 [baudrate][databit][parity][stopbit]
Description
Example:
u
Com2 is assigned for RS485. This command enables you to
The second serial port
set up the transmission speed(baudrate),data bit(databit), parity check type (parity)
and stop bit(stopbit).
The transmission speed parameter [baudrate] allows the following settings: 300, 600,
1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200. The port speed and
device speed must match.
The number of data bits can be 7 (for true ASCII) or 8 (for any kind of data, as this
matches the size of a byte),
The parity check code can be set to none (0), even (1), or odd (2). None(0) means
that no parity bit is sent at all. Even (1) means applying even parity check, each set
of transmitted bits must have an even number of set bits. Odd (2) means applying
odd parity check, each set of transmitted bits must have an odd number of set bits.
Stop bit is used in asynchronous communications to indicate the end of a piece of
data.
Parameters
Parameter Description
