If the check fails, the receiving program sends a NAK character and the sending program
retransmits the packet.
Modifying Serial Communication Parameters
In actual applications, you need to make the serial interface baud rate higher to save updating time or
make it lower to guarantee transmission reliability. This section introduces how to adjust the serial
interface baud rate.
Enter the BootWare main menu.
z
For the WA2200 series, WA2600 enhanced APs, and WA2600 outdoor APs, select 2 to enter the
serial interface submenu, and then select 3 from the submenu to modify the baud rate.
z
For the WA2600 series indoor APs, select 2 to enter the serial interface submenu, and then select
5 from the submenu to modify the baud rate.

|Note:'*'indicates the current baudrate |
| Change The HyperTerminal's Baudrate Accordingly |
|---------------------------
|<1> 9600(Default)* |
|<2> 19200 |
|<3> 38400 |
|<4> 57600 |
|<5> 115200 |
|<0> Exit |
============================================================================
Enter your choice(0-5):
Select an appropriate baud rate. For example, select 5 for 115200 bps. The following information
appears:
Baudrate has been changed to 115200 bps.
Please change the terminal's baudrate to 115200 bps, press ENTER when ready.
Now that the serial interface baud rate of the AP has been changed to 115,200 bps while that of the
terminal is still 9,600 bps, the AP and the terminal cannot communicate with each other. Change the
baud rate to 115,200 bps in HyperTerminal.
Step1 Disconnect the terminal connection in HyperTerminal, as shown below:
Figure 7-2 Disconnect the terminal connection
Step2 Choose File > Properties. In the Properties dialog box, click Configure… and select 115,200 in the
Bits per second drop-down list box.
