3Com Router 5000 Family and Router 6000 Family baudrate ● 19
Command Reference
After a synchronous/asynchronous serial interface makes the
synchronous/asynchronous switchover, the baud rate of the interface resumes the
default baud rate in the new operating mode.
When setting baud rate for a serial interface, you should take into consideration the
elements such as operating mode (synchronous/asynchronous mode) and the electric
specifications of the connected external cable. In addition, you should note that the
baud rate of asynchronous serial interface is only significant for the connection
between router and modem. If two modems are concerned, the baud rate between
them will be directly negotiated by themselves. Therefore, different baud rate settings
can be set on the routers at the two ends of a connection, if the routers are working
in asynchronous mode. In synchronous mode, however, the router working as DCE
will determine the baud rate for the line transmission. Therefore, you need to set
baud rate at the DCE side in this case.
