Description
Number of Rings to Auto-Answer:
modem automatically answers a call. ATS0=0 disables autoanswer completely.
Ring Counter:
Escape Character:
character. Values greater than 127 disable escape.
Carriage Return Character:
Line Feed Character:
Backspace Character:
character. Values greater than 32 disable backspace.
Wait Time Before Blind Dialing or for Dial Tone:
waits after it goes off-hook before it begins to dial the phone number.
Wait Time for Carrier, Silence, or Dial Tone:
carrier signal before aborting a call. Sets the wait for silence time for the @ dial
modifier. Sets the time the modem waits for a dial tone after encountering W in the
dial string.
Pause Time for Dial Delay:
character in a dialing command.
Carrier Detect Response Time:
carrier must be present before the modem considers it valid.
Lost Carrier to Hang Up Delay:
the modem disconnects.
DTMF Tone Duration:
Escape Prompt Delay (EPD):
allowed between receipt of the last character of the three escape character
sequences from the computer and the sending of the OK result code to the
computer (escape code guard time).
Remote Configuration Escape Character:
configuration escape character. ATS13=0&W disables remote configuration. For
use with the MT5600BA and MT5600BR only.
Dialup Backup:
connection before it checks for a restored lease line. Zero disables dial backup. For
use with the MT5600BA and MT5600BR only.
Dialup Connection:
before it attempts a dial-up connection. For use with the MT5600BA and
MT5600BR only.
Sleep Inactivity Timer:
normal mode with no detected telephone or serial port activity before it enters low-
power sleep mode. The timer is reset upon any serial port or telephone line activity.
Delay to DTR OFF:
(sync) ignores DTR while taking the action specified by &D .
RTS to CTS Delay:
OFF-to-ON transition on RTS before the modem turns CTSON. Applies to
synchronous operation only.
