Motorola g20 - Table 136. MIPSTAT Parameters

AT Commands Reference
258 98-08901C68-O
The following table shows the MIPSTAT parameters.
4.15.2.10 MIPXOFF, Flow Control - Xoff
This command is the unsolicited response that the g20 sends to the terminal to stop sending data when it does not have enough
memory to process new +MIPSEND requests. The g20 uses the accumulating buffer prior to pushing data into the protocol
stack. This memory resource is protected by a Xoff_upper watermark.
Example
+MIPXOFF: //The g20 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.
4.15.2.11 MIPXON, Flow Control - Xon
This command is the unsolicited event that the g20 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.
Example
+MIPXON: 1 //The g20 pushed the data into the protocol stack on socket 1 and is able to handle more
data from the terminal.
