Technical data

ATS7=<n> Default value is set to zero (e.g., modem will use protocol-specific default value).

Modem mode: time to wait for carrier. Sets the time in seconds that the modem will

wait for a carrier before hanging up. <n> is a range from 0 to 255 seconds.

Fax mode: time to wait for connect. Sets the time in seconds that fax will wait for

connection before hanging up. Suggested value is 200 seconds. Values less than 10

seconds are ignored. The carrier waiting time starts after the connection was

established and is set to 60 seconds.

ATS9=<n> Carrier Detect Response Time. Sets the time in tenths of a second that a carrier must

be present before the modem considers it valid. <n> is a range from 0 to 255 tenths

of a second. This register is only implemented for compatibility reasons. Writing to

this register does not affect the Carrier Detect Response time.

ATS10=<n> Delay between carrier loss and hang up. Sets the time in tenths of a second that the

modem waits before hanging up after a loss of carrier. <n> is a range from 0 ... 255

tenths of a second.
