3.2.2.8 &K - Flow Control
This command defines the DTE/DCE (terminal/modem) flow control mechanism.
Syntax
&K[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
Result Codes
OK
ERROR
3.2.2.9 &M - Asynchronous/Synchronous Mode Selection
This command is included for compatibility only and has no effect other than returning a result code. The only valid values
are 0-3.
Syntax
&M[<mode>]
Defined Values
<mode > Decimal number corresponding to the selected value: 0-3.
Result Codes
OK
ERROR
3.2.2.10 &Q - Sync/Async Mode
This command determines the DTR operating mode. (Also, see \N.)
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:
Result Codes
3-14
Command Reference Manual
0 Disables flow control.
3 Enables RTS/CTS flow control. (Default for data modem modes.)
4 Enables XON/XOFF flow control.
5 Included for compatibility only and has no effect other than returning an OK result code.
6 Included for compatibility only and has no effect other than returning an OK result code.
<value> = 0, 3, 4, 5, or 6.
Otherwise.
<mode> = 0 to 3.
Otherwise.
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).
OK <mode > = 0-3, 5, 6.
ERROR Otherwise.
