S25
Detect DTR Change
S25
defines the minimum amount of time that DTR has to remain
off (i.e., on-to-off-to-on transitions) before the modem will perform
the function specified by ‘& Dn’command. A change in DTR that
persists for a shorter time than the valued specified in S25 is ig-
nored by the modem (see ‘&Dn’
command).
Range: 0-255 (1/100 of a second)
Default: 5
S26
RTS to CTS Delay Interval
S26 is only used for synchronous operation. This register, when
the modem is configured for &R0, specifies the time delay be-
tween an off-to-on transition on RTS and turning CTS on.
Range: 0-255 (1/100 of a second)
Default: 1 (is equal to second)
