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 initial-

ization. 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_be-

gin_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 re-

ceived 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 discon-
nect 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 char-
acters from the

DTE

. Default:

100

periodic_reset_timeout_msecs [dword 0–4294967295]: How often a reset
sequence should be done to verify modem integrity. It is understood that some
modems may periodically hang or go into a disabled power saver type of mode
or that they may be turned off and on but the

DSR

modem control change is not

detected possibly because TAPI is being used. Therefore, the driver will reset
the modem when it is idle for this amount of time. Setting this to 0 will disable
this periodic reset feature. Default:

600000

receive_image_modulation_timeout_msecs [dword 0-65535]: How long to
wait without receiving any image data before canceling the reception of image
data. There is a USR modem that sometimes fails to send a

DLE

ETX

sequence

at the end of image data. By having this timeout short enough, the driver will
abort the image receive in a timeliness manner so as to receive one of the sub-
sequent end of page commands. Default:

3000
