to keep up with the modem modulation throughput due to extra DLE escaped
characters. Default:

38400

dtmf_detection_begin [string]: When the

line_type

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:

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

Default:

200

enable_init_flow_control [boolean]: This is for the rare modems that return

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 "

" command. There are some modems that upon sending an

from a subsequent command, must have time to get ready to receive new
characters from the

DTE

. Default:

100
