4.8 New function

TCP password authentication

This feature is available only on the module as a TCP server, when the TCP client connection
module, the module will authenticate each connected tcp.
Each TCP client first data is the "password+0x0d+0x0a" (the password is Webpage
authentication password). The default password is "admin", so the first piece of data should be
"0x61 0x64 0x6D 0x69 0x6E 0x0D 0x0A" (Hex). If the password is correct, the module returns
"OK", on the other hand, return to the "NO" and disconnect.
The TCP connection of this function can be Webpage in "TCP connection password
authentication" is opened or disable. Please refer to the specific "5.1.6" section.

4.8.1 Registered Package ID/MAC

This function only applies to the module as a TCP client, in front of the data when module
connected to the server with two bytes of ID (ID the range is 0 ~ 65535, the high byte before, and
the low byte behind) plus two bytes ID radix-minus-one complement(or upload 6 bytes MAC
address).Module is the default ID is 1111(MAC:D8B04CF20000), for example, is sent to the
server when the first four bytes "0x57 0x04 0xfb 0xa8"(or "0xD8 0xB0 0x4C 0xF2 0x00 0x00").
There are two ways to upload their own id: one is to upload their own ID/MAC for connection to
the server for the first time;The other is a plus ID/MAC in front of each data.
Registered Package related parameter is set in the "serial port and other Settings" section of the
web, build joint function of ID/MAC for the first time, and each data with the function of ID/MAC
are disabled by default.
Note: the function of the upload MAC supported in V5.01.14 and above version.

4.8.2 Self-adaption Baudrate

This feature, please cooperate with our company's virtual serial port software use.
Use a serial port connected module, and use the at command "at + AABR = on" open this
function and restart.In the USR - VOCM software "synchronous baud rate (RFC2217 similar)" is
selected, the following figure.
Specific setup process, please refer to the AT command section(5.2.2.2.39).
RFC 2217
Figure 24
In this way, the module of baud rate will be as the USR-VCOM to change at any time, and don't
have to restart the module.If restart the module, baud rate and will come back to before.
