	CreateServerSocket
Creates a listening socket on the selected channel and port ready to accept incoming web page requests.
- BYTE	Channel

- BYTE	Port_Hi

- BYTE	Port_Lo

- BYTE	Return

GetInValue

	GetInValue
Returns the string value of a Request parameter

Property reference

	Properties
	Label
Label used to help identify the component on the panel.
	Max Channels
Max number of concurrent channels allowed
	I2C Address
I2C address of the module - bit 0
	HTML Source
	HTML Source
Sets the method for streaming data, we can either host it loacally using a property or refer to external files.
	Max Pages
Maximum number of pages we can serve using the embedded page type webserver.
	Name Page 1
Name of HTML page 1 - index.htm is the default page that will be presented.
	HTML Page 1
Embedded HTML code used for page 1
	Name Page 2
Name of HTML page 2
	HTML Page 2
Embedded HTML code used for page 2
	Name Page 3
Name of HTML page 3
	HTML Page 3
Embedded HTML code used for page 3
	Name Page 4
Name of HTML page 4
	HTML Page 4
Embedded HTML code used for page 4
	Connections
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
