3.3. Environment Setup
Environment variables such as the IP address, the serial port rate,
the connection port number, and the serial communication mode can
be changed by using AT command, the internal shell applications of
ezTCP, and ezConfig.
3.3.1. Environment Setup in ATC mode
After changing the environment setup value, you must use the +PWP
command. +PWP is used to store the changed value in the actual
EEPROM. If the ezTCP power is turned on or EEPROM configuration
is changed by +PWP command, NO CARRIER message is displayed.
The examples listed below are for setting each item:
AT+PLIP=aa.bb.cc.dd : ezTCP's IP Address
>>
<< OK
AT+PGIP=bb.cc.dd.ee : Gateway IP Address
>>
<< OK
AT+PSM=255.255.255.0 : Subnet Mask
>>
<< OK
AT+PLP=1470 : ezTCP's Listening TCP Port
>>
<< OK
AT+PTO=10 : Reception Time Out
>>
