+MIPSETS: 0

OK

+MIPSEND=1,"444444"

//Passing 3 bytes of data to the G24-L socket 1

Xoff and Xon Example

In this example, it is assumed that the buffer size is 1500 and that some kind of error happened on
the protocol stack.

+MIPSEND=1,"A344343ABC343438980BC...AB4" //Passing data to G24-L socket 1
+MIPSEND:1,1200

//(Note: Size remaining in socket 1 accumulating buffer is 1200 bytes.)

+MIPSEND=1,"A344343ABC343438980BC...A23"

+MIPSEND:1,0

//(Note: No free space in buffer.)

+MIPXOFF: 1

//The G24-L detects that the accumulating buffer on socket 1 has no

free space to accumulate data and data cannot be sent to the protocol stack.

From this point on, the terminal is not allowed to send data until it receives the +MIPXON
command.

+MIPSEND=1,A344343ABC343438980BC...AB4//Terminal disregards the Xoff request of G24-L and keeps
sending //(Note: The terminal does not stop.)
