sub function Spi_Ethernet_UserTCP(dim remoteHost as ^byte, dim
remotePort 

as word, dim localPort as word, dim reqLength as word)

- 

0

- there should not be a reply to the request. 

- Length of TCP/HTTP reply data field - otherwise. 

This is TCP module routine. It is internally called by the library. The user
accesses to the TCP/HTTP request by using some of the Spi_Ethernet_get rou-
tines. The user puts data in the transmit buffer by using some of the Spi_Ether-
net_put routines. The function must return the length in bytes of the TCP/HTTP
reply, or 0 if there is nothing to transmit. If there is no need to reply to the
TCP/HTTP requests, just define this function with return(0) as a single state-
ment. 

Parameters:

- 

remoteHost:

client's IP address. 

- 

remotePort:

client's TCP port. 

- 

localPort:

port to which the request is sent. 

- 

reqLength:

TCP/HTTP request data field length. 

Note: The function source code is provided with appropriate example projects.
The code should be adjusted by the user to achieve desired reply.

Ethernet module has to be initialized. See Spi_Ethernet_Init.

This function is internally called by the library and should not be called by the
user's code.
