S Registers

Note: To change a setting use ATSr=n, where r is the register and n is a decimal value from 0 − 255 (unless otherwise indicated).

8-16

S16 0 Reserved

S17 0 Reserved

S18 0 Test timer for &T loopback testing. Sets the time in seconds of testing before the modem automatically times out and terminates

the test. When set to 0, the timer is disabled. Valid range is 1-255.

S19 0 Sets duration, in minutes, for inactivity timer. This timer activates when there is no data activity on the phone line; at time-out

the modem hangs up. S19 = 0 disables the timer.

S20 0 Reserved

S21 10 Sets length, in 10-millisecond units, of breaks sent from the modem to the computer; applies to MNP or V.42 mode only.

S22 17 Stores ASCII decimal code for the XON character.

S23 19 Stores ASCII decimal code for the XOFF character.

S24 0 Reserved

S25 20 Sets duration, in hundredths of a second, of a true DTR drop. Prevents modem from interpreting random glitches as DTR loss.

(Most users will use the default; this register is useful for compatibility with older systems and operating software.)
