+MIPPUSH=1 //Terminal asks the G24 to flush the buffer in sockets 1 and 2
+MIPPUSH:0
+MIPPUSH=2
+MIPPUSH:0
+MIPCLOSE=1 //Terminal closes sockets 1 and 2
+MIPCLOSE:1
OK
+MIPCLOSE=2
+MIPCLOSE:2

+MIPCALL=0 //Terminal hangs up the link
OK
+MIPSETS=1,120 //Asking the G24 to accumulate 120 bytes on socket 1 prior to sending
+MIPSETS: 0
OK
+MIPSEND=1,"444444" //Passing 3 bytes of data to the G24 socket 1
Note: Size remaining in socket 1 buffer is 1497 bytes.
+MIPSEND:1,1497
+MIPPUSH=1 //At this point, the terminal can decide on flushing the remainder to
the stack
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 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 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.
