Syntax
+MIPDATA: <Socket ID>,<Number of received data bytes>
The following table shows the MIPDATA parameters.
Example
+MIPDATA: 1,1372
MIPXOFF, Flow Control - Xoff
This command is the unsolicited response that the G24 sends to the terminal to stop sending data
when it does not have enough memory to process new +MIPSEND requests. The G24 uses the
accumulating buffer prior to pushing data into the protocol stack. This memory resource is
protected by a Xoff_upper watermark.
Event
+MIPXOFF: <Socket ID>
Example
+MIPXOFF: //The G24 detects that the accumulating buffer 1 has reached its Xoff
watermark.
From this point, the terminal is not allowed to send data, until it receives the +MIPXON
command.
MIPXON, Flow Control - Xon
This command is the unsolicited event that the G24 sends to the terminal when it detects that it
has free memory in the accumulating buffer and can process new +MIPSEND requests, after the
+MIPXOFF event.
Event
+MIPXON: <Socket ID>
Example
+MIPXON: 1 //The G24 pushed the data into the protocol stack on socket 1 and is
able to handle more data from the terminal.
