S6

2

Sets the number of seconds the modem will wait before dialing. If Xn

 

 

is set to X2 or X4, S6 determines the timeout length when no dial tone

 

 

is detected.

 

 

S7

60

Sets the number of seconds the modem will wait for a carrier. Often

 

 

used to select a longer duration when the modem is originating an

 

 

international connection.

 

S8

2

Sets the duration (in seconds) for the Dial command pause option (,).

S9

6

Determines the length of time (in tenths of a second) the remote

 

 

modem's carrier signal must continue in order to be recognized by the

 

 

RMM.

 

 

S10

7

Sets the length of time (in tenths of a second) the modem will wait

 

 

after loss of carrier before hanging up. Allows the modem to

 

 

distinguish between a line hit (or other momentary break) from a true

 

 

disconnect (hang up) by the remote modem.

 

 

Although it is not recommended to connect to a line with call waiting,

 

 

the S10 register can be adjusted upward to prevent the modem from

 

 

misinterpreting the second call signal as a remote disconnect. If call

 

 

waiting is a problem, it is preferable to contact your phone company to

 

 

determine the command to temporarily disable call waiting (typically

 

 

*70W). For example: ATDT *70W phone number.

 

 

Note: If S10 = 255, the modem will not hang up when the carrier is

 

 

lost. Dropping DTR hangs up the modem.

S11

70

Sets the duration and spacing (in milliseconds) for tone dialing.

S12

50

Sets the duration (in fiftieths of a second) of the guard time for the

 

 

escape code sequence (+++).

S13

0

Bit-mapped register. Select the bit(s) you want ON and set S13 to the

 

 

total of the values in the Value Column. For example, ATS13=17

 

 

enables bit 0 (value is 1) and bit 4 (value is 16).
