S31 ASY Interface Speed
Units: N/A
Default: 0
Range: 0-11
Register S31 sets the speed and data format for the ASY port to which you are currently connected.
The default value for ASY 0 is 0, such as the port speed/data format is not set to a specific value, it is
determined automatically from the AT commands that you enter.
The default value for ASY 1, 2, and 3 is 3, meaning the ports only accept AT commands at
115,200bps (8 data bits, no parity and 1 stop bit).
To set the speed of one of the ports to a particular value, set the appropriate register to the required
value from the following table:
S31 Port Speed (bps)
0 Auto-detect
1 Reserved
2 Reserved
3 115200
4 57600
5 38400
For example, to change the speed of ASY 1 to 38,400bps, connect your terminal to that port with
the speed set to 9600bps. Enter the command:
ats31=5
Then change the speed of your terminal to 38,400bps before entering any more AT commands.
When entering the ATS31=n command, the data format selected becomes the data format for all
further commands.
The auto-detect option is only available for ASY0 and ASY1.
S33 DTR Dialing
Units: N/A
Default: 0
Range: 0, 1
S33 enables or disables DTR dialing for the port. When DTR dialing is enabled, the router dials the
number stored for that port (see AT&Z) when the DTR signal from the terminal changes from Off to
On.
S45 DTR Loss De-Bounce
Units: 0.05 seconds
Default: 5
Range: 1-255
The value in S45 determines the length of time for which the DTR signal from the terminal device
must go off before the router acts upon any options that are set to trigger on loss of DTR. Increasing
or decreasing the value in S45 makes the router less or more sensitive to "bouncing" of the DTR
signal respectively.
