rings_before_answer [dword 0–255]: Number of rings before modem ac-
cepts call. Default: 
1
.
ser_device_name [string]: Win32 name for the serial port in the format of 
COMXXX where XXX can be 001–999. This does not need to be specified if 
the 
tapi_modem_name
is specified. Format: Up to 6 characters.
init_string [string]: This is the basic modem initialization string. It should reset 
the modem and init the required flow control. Format: Up to 80 characters. 
Default: 
&F&C1&D2V1E0S0=0S7=90^^
.
All modem commands start with AT, so this string does not need AT. The sym-
bols in the string mean the following: 
^
2-second pause
\
Carriage return. There is a wait of
init_string_timeout_msecs
after carriage return to wait
an
OK
to be returned.
\\
Specifies a single
\
^^\
this is interpreted as
\^^
init_string_timeout_msecs [dword 0–65535]: How long to wait for re-
sponse after 
CR
in the
init_string
if there are no 2-second pauses before or
after the
CR
. Default:
5000
.
close_string [string]: Determines what commands should be sent to a fax mo-
dem to restore it to its normal state of operation after the application has fin-
ished using it. See 
init_string
description for string format explanation.
Default:
Z^^
.
io_buffer_size [dword 0–65535]: This is the size of the image buffer. The 
necessary buffer size depends on host CPU speed and load as well as connect 
speed. This buffer directly adds to driver page locked memory use so should be 
as small as possible. However, too small a buffer will cause faxes to fail. De-
fault: 
20480
.
show_console_scroll_back_buffer_size [dword 0–4294967295]: When 
the debug output is 
CONSOLE
, this is how big of a buffer to be used for scroll-
back. Default:
282144
.
show_ring0_buffer_size [dword 0–4294967295 ]: How big of buffer for 
the page locked debug buffer that ring0 code writes to and ring3 code extracts 
from (on a thread) to the debugging output. This should be larger for when us-
ing serial capture mode since so much more data is written for debug. It should 
probably be only about 1K for when using T.30 debug since the frequency and 
amount of T.30 debug is small enough that the ring3 code can easily keep up 
writing to the show output. Default: 
65536
.
debug_show_file_path [string(256)]: Partial path or complete path and file 
name of where to create debug file. If the 
debug_show_output
is set for
CON-
SOLE
and the
debug_show_file_path
is specified in the registry, then you can
get both
CONSOLE
and
FILE
debug output simultaneously. This is a device spe-
