S24 - Sleep Inactivity Timer
Sets the length of time, in seconds, that the modem will operate in normal mode with no detected telephone
line or DTE line activity before entering low-power sleep mode. The timer is reset upon any DTE line or
telephone line activity. If the S24 value is zero, neither DTE line nor telephone inactivity will cause the modem
to enter the sleep mode.
Range:
0-255 seconds
Default:
0
S25 - Delay to DTR
Set the length of time that the modem will ignore DTR for taking the action specified by &Dn. Its units are
seconds for synchronous modes and one hundredths of a second for other modes.
Range:
0-255
Default:
5
S26 - RTS to CTS Delay
Sets the time delay, in hundredths of a second, before the modem turns CTS ON after detecting an OFF-to-
ON transition on RTS when &R0 is commanded.
Range:
0-255 hundredths of a second
Default:
1
