There is a possibility that you will get some funny characters or no response resulting from
the different baud rate settings on the communications software and the WINC 900A. If
this happens, please reset the WINC 900A back to the manufacturer’s default setting --
9600 bps as instructed below.
Whenever you need to clear the settings, you can issue AT command AT&F to reset the
WINC 900A to the original factory default conditions. An alternative method for
accomplishing this is to hold the reset button on the front panel and turn on the power of
WINC 900A. (please refer to Fig. 4-3) A pencil, pen or other sharply pointed object is
required to access the button through the hole on the front panel.
Step 4: Save the configuration settings
of your communications of software
If you already completed the steps above without problems, you may select the “Save” from
the “File” option in the MS-Windows Terminal and save the configuration settings for the
future before you leave Terminal.
If you still have problems communicating with the WINC 900A from your computer, please work on
the followings step by step, and then start all over again from the beginning of this chapter or walk
through our recommendation below.
1.
Contact your computer hardware engineer, verify the availability of the serial port (com port) on
your computer, and working on this until the serial port is available to you.
2.
Connect your serial port with an external modem and work on the communication software
setting until you get the dial tone, dialing out successfully.
3.
Replace the external modem with WINC 900A. At this point, go through the factory default
setting process above to make sure that 9600 is the default baud rate on WINC 900A.

Please work from the beginning of chapter 4.0 again.
