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 atz: Reset ) 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.
