Overview and How To Enter Each Mode
4.1.1.
Overview
There are 3 modes (normal mode, serial configuration mode, ISP mode) in ezTCP.
ezTCP does normal operation in the normal mode, and it configures environmental
variables(especially wireless LAN related item), and it perform firmware upgrading in
ISP mode.
The operation modes of ezTCP are normal communication mode, serial configuration
mode and ISP mode. Major differences among the modes are as follows.

How To Enter Each Mode
z
Normal mode
ezTCP operates in the normal mode if a PCMCIA card is inserted. ezTCP attempt to
connect a link to wireless LAN at first. And LINK LED is on after connection.
z
Serial configuration mode
ezTCP operates in the serial configuration mode if it is turned on without LAN card
insertion. In serial configuration mode, all environmental variables can be set including
wireless LAN related items.
z
ISP mode
After connecting PC and ezTCP via serial cable, run serial terminal program(i.e. Tera
Term Pro) which can transmit binary file with 115200bps baudrate. As soon as it is
turned on, if you input <CR>(0x0d), you can see a “000” message. If you should input
“flash”, then you can enter ISP mode.
Following is the message when ezTCP enters to ISP mode.
