Command Reference
Data Command Set - 35
Note: When the &Q0 is issued to select the mode, the subsequent connect message will report the DCE speed 
regardless of the W command and S95 settings. 
Syntax 
&Q[<mode>] 
Defined Values 
<mode >  Decimal number corresponding to the selected mode: 
0  Selects asynchronous operation in normal mode (speed 
buffering) 
1  Selects asynchronous operation in normal mode (speed 
buffering) 
2  Selects asynchronous operation in normal mode (speed 
buffering) 
3  Selects asynchronous operation in normal mode (speed 
buffering) 
5  Selects asynchronous operation in error correction mode 
6  Selects asynchronous operation in normal mode (speed 
buffering) 
Result Codes 
OK  <mode > = 0-3, 5, 6. 
ERROR Otherwise. 
+IPR - Fixed DTE Rate 
This numeric extended-format parameter specifies the data rate at which the 
modem will accept commands during online operation. It may be used to select 
operation at rates at which the modem is not capable of automatically detecting 
the data rate being used by the DTE. Specifying a value of 0 disables the function 
and allows operation only at rates automatically detectable by the modem. The 
specified rate takes effect following the issuance of any result code(s) associated 
with the current command line. 
The <rate> specified does not apply in OnLine Data State if Normal Mode (Direct 
Mode) of operation is selected.
