CNG tone is detected or

dtmf_digit_count

number of digits are collected.

Default:

NORMAL

.

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

.

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 subsequent end of page commands. Default:

3000

.

send_buffer_empty_flow_control [boolean]: If enabled and the send
image buffer does not contain a complete scan line or ECM frame, this causes a
particular byte (0 or current ECM flag byte) to be continually sent when the
serial helper drivers buffers become empty. This will prevent the modem from
dropping carrier when its buffers run dry. If this is disabled and you have a
latent filling of the drivers send image buffer by ICANFax, there is the possibility
that you might experience a send under-run error because the modem drops
carrier before all the page data has been sent. Default:

true

.

send_image_modulation_timeout_msecs [dword 0–4294967295]: This
is how long to wait after sending a block of send image data to the modem
before assuming the modem is having problems. This number should be large
enough to account for the time done by the modem and serial driver buffering.
Default:

200000
