%Q – Report Line Signal Quality
Supported by: TDW-33 TD-36 TD-36 485 TR-36 TR-36B
Description:
Command always respond with OK in on line command mode, ERROR will be sent on
all other cases.
For compability reasons only. See also AT&V1

&Qn – Asyncronous Mode
Supported by: TDW-33 TD-36 TD-36 485 TR-36 TR-36B
Description:
This command is used to control connection modes permitted. It is used in conjunction
with S36 and S48.
See also AT\Nn.
Syntax:
AT&Q<n>
Parameters:
<n>
0: Selects direct asynchronous operation. The value 000b is written to S27 bits 3, 1,
and 0, respectively.
5: The modem will try to negotiate an error-corrected link. The modem can be con-
figured using S36 to determine whether a failure will result in the modem returning
on hook or will result in fallback to an asynchronous connection. The value 101b
is written to S27 bits 3, 1 and 0 respectively (Default).
6: Selects asynchronous operation in normal mode (speed buffering). The value 110b
is written to S27 bits 3, 1 and 0, respectively.
Command example Possible responses Note
AT&Q<n> OK
ERROR If not valid
S register: The value is written to S27 (see description).
