Command Reference
baudrate
Purpose Use the baudrate command to set the baud rate of a serial interface.
Syntax baudrate baudrate
Parameters baudrate
Baud rate of the serial interface (in bps). Valid values
are 300 to 115,200 for an asynchronous serial
interface and 1200 to 2,048,000 for a synchronous
serial interface.
Default By default, the baud rate is 9,600 bps on the asynchronous serial interface and
64,000 bps on a synchronous serial interface.
Example Set the baud rate of the asynchronous serial interface at DCE side to 115200 bps.
[3Com -Serial0/0/0] baudrate 115200
View This command can be used in the following views:
■ Serial Interface view
Description The following are the baud rates available with asynchronous serial interfaces:
300 bps, 600 bps, 1,200 bps, 2,400 bps, 4,800 bps, 9,600 bps, 19,200 bps, 38,400
bps, 57,600 bps, 115,200 bps
The following are the baud rates available with synchronous serial interfaces:
1,200 bps, 2,400 bps, 4,800 bps, 9,600 bps, 19,200 bps, 38,400 bps, 57,600 bps,
64,000 bps, 72,000 bps, 115,200 bps, 128,000 bps, 192,000 bps, 256,000 bps,
384,000 bps, 512,000 bps, 1,024,000 bps, 2,048,000 bps
Note that the baud rates of 192,000 bps, 256,000 bps, 512,000 bps, 1,024,000 bps,
and 2,048,000 bps are available with some types of serial interfaces only. You can
know whether these baud rates are available by reading the prompt message
displayed on the screen for this command.
The baud rate range available with synchronous serial interfaces depends on the
applied physical electric specifications.
■ V.24 DTE/DCE supports the range of 1200 bps to 64000 bps
■ V.35 DCE/DCE, X.21 DTE/DCE, EIA/TIA-449 DTE/DCE and EIA-530 DTE/DCE
supports the range of 1200 bps to 2048000 bps
