Note: if you intend to set up any one of the recovery time, forward time, max age, or
hello time manually by using console commands, you are required to set up these
values all together by using the corresponding console commands, too. If you do not
assign specific values for these settings, they will become preset values (or default
values if no values were previously assigned)
com1 [baudrate][databit][parity][stopbit]
Description
The first serial port Com1 is assigned for RS232. This command enables you to 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.
