to keep up with the modem modulation throughput due to extra DLE escaped
characters. Default:
38400 .
dtmf_detection_begin [string]: When the line_type is DTMF_PROMPT , this
command is sent to the modem before answering. It should cause the modem
to go off hook, emit a prompt tone if possible and collect and report received
DTMF digits. This has the same formate rules as the
init_string , plus a /
{ sequence is translated to a DLE ( 0x10 ) character and a /} sequence is
translated to a ETX ( 0x03 ) character. Format: Up to 80 characters. Default:
#CLS=8A .
dtmf_detection_end [string]: This is what needs to be sent to the modem to
get it out of the state that the
dtmf_detection_begin put it in. It is sent by the
driver when either the 6 second interdigit DTMF timeout occurs or the
dtmf_terminate_digits is received. This has the same format rules as
dtmf_detection_begin . Format: Up to 80 characters.
dtmf_digit_count [dword 0–31]: Max number of DTMF digits to receive.
Setting 0 disables this. Default:
0 .
dtmf_terminate_digit [string]: The received DTMF digit that causes the driver
to terminate DTMF digit collection being done by the modem by sending the
dtmf_detection_end string. Leave blank to not use a terminate character.
Format: 0 or 1 characters, typically # or *. Default: # .
dtr_toggle_msecs [dword 0–65535]: This is how long to keep the DTR line
low during reset or close so that a modem will hangup the line and return an
OK .
Default: 200 .
enable_init_flow_control [boolean]: This is for the rare modems that return
OK following ATZ and have CTS low because they are unable to accept another
command. This will probably never be used since ATZ is not sent for user
initialization. Default: false .
hangup_timeout_msecs [dword 0–65535]: This is how long to wait for ATH0
command to complete. Default: 2000 .
line_type [string]: When dtmf_prompt is specified, the
dtmf_detection_begin_string will be sent at the start of the call and received
DTMF digits will be collected from the modem up until either a
dtmf_terminate_digit is received or a 6 second inter-digit timeout occurs or a
CNG tone is detected or dtmf_digit_count number of digits are collected.
Default: NORMAL .
next_ring_response_timeout_msecs [dword 0–65535]: This is how many
msecs to wait after a ring from the modem before resetting the internal ring
counter. This will only apply for
rings_before_answer greater than 1 and when
not using TAPI. Default: 7500 .
on_hook_msecs [dword 0–65535]: This is the minimum amount of time after
the modem goes on hook from a prior connection before the driver will start a
new connection (dial). This will allow the phone system to have time to
disconnect the call upon noticing the modem on hook. Default:
200 .
pause_before_send_command_msecs [dword 0–65535]: This specifies
how long to pause when the protocol state is idle, answering, or dialing, before
sending the "
AT " command. There are some modems that upon sending an OK
from a subsequent command, must have time to get ready to receive new
characters from the
DTE . Default: 100 .
