Description

 

 

 

 

 

Guard Time: S12 is used to specify guard and detect times used for the Hayes and TIES

 

 

escape sequences.

 

 

 

For the Hayes Escape Sequence, S12 specifies the minimum-delay timer (or guard time) before

 

 

and after the three escape characters that is required for the modem to detect the Hayes

S12

50

Escape Sequence.

 

For TIES, S12 specifies the maximum time limit that must elapse after receiving the three

 

 

 

 

escape characters (and no other characters) before sending an OK message to the DTE.

 

 

Range:

0–255 (1/50 of a second)

 

 

Default:

50 (equals 1 second)

 

 

 

 

 

Bit-Mapped Options: S14 is a read-only register that indicates AT command settings.

Modem Test Timer: S18 specifies the length of time that the modem conducts a data mode

 

 

(except for V.90 and V.92) loopback test using the &Tn command. After timing out, the modem

S18

0

returns to command mode. Setting S18 to ‘0’ disables the modem test timer; the loopback test

must be terminated by issuing the appropriate escape sequence followed by an AT&T0 or ATH.

 

 

 

 

Range:

0–255 seconds

 

 

Default: 0 seconds
