Modifying Serial Port Parameters

Sometimes, we need to change the serial baud rate to higher in order to save upgrading time, or to
lower to guarantee transmission reliability. This section depicts how to adjust serial baud rate.
Enter <2> under the main BootROM menu to enter the serial submenu. Then, enter <5>, and the
system prompts to change serial baud rate.
========================<BAUDRATE SET>=======================
|Note: Change The HyperTerminal's Baudrate Accordingly,
| Press 'Enter' to exit with things untouched.
|--------------------<Baudrate Available>-------------------|
| <1> 9600(Default)
| <2> 19200
| <3> 38400
| <4> 57600
| <5> 115200
| <6> Exit
=============================================================
Enter Your Choice(1-6):
Select a baud rate, <5> for 115200 bps for example. The following prompt appears:
Change the baudrate on PC side first!
Since the router serial baud rate is modified to 115200 bps, whereas the terminal baud rate remains to

same as that for software download.
Perform the following operation:
