chars because the driver assumes the last 2 bytes are CRC bytes). Default: false.
pause_before_frh_msecs [dword 0–65535]: Some modems would not be able to
understand the AT+FRH=3 command if a slight pause is not inserted following a previous
response or command. Since this is usually a very small delay, this was previously implemented
in 16 bit as a software timing loop because one clock tick (54ms) was too long to wait. NT has a
min of 10ms clock interrupt timing, so this may cause problems and the driver may need to be
modified to use a software delay timing loop. Default: 20.
receive_frame_response_timeout_msecs [dword 0–65535]: How long to wait for modem
response (OK, +FCERROR, NO CARRIER...) after receiving a DLE/ETX terminated frame.
Default: 3000.
receive_v34_image_modulation_timeout_msecs [dword 0–65535]: How long to wait
without receiving any image data before canceling the reception of image data when doing v.34
fax receive. This is quite different than the receive_image_modulation_timeout_msecs because
the modem is responsible for removing flags and bit stuffing and it may be that the sending unit
can add up to 35 seconds of flags between ECM frames so as to allow for send flow control. It is
valid and has been witnessed that the class1 driver might not receive any data for several
seconds due to the sender scanning latency. Default: 35000.
send_frame_response_timeout_msecs [dword 0–65535]: How long to wait for modem
response after sending frame data. Default: 90.
software_frs_20_msecs [dword 0–65535]: How long to wait when switching the modulation
from receive to transmit. If this is set to 0, then AT+FRS=20 will be used. Default: 300.
start_receive_image_timeout_msecs [dword 0–65535]: How long to wait for modem
response after sending AT+FRM=
Default: 3000.
start_send_image_timeout_msecs [dword 0–65535]: How long to wait for modem
response after sending AT+FRM=
3000.
t1_seconds [dword 0–65535]: T.30 T1 timer. Default: 35.
t2_msecs [dword 0–65535]: T.30 T2 timer. Default: 6000.
t4_msecs [dword 0–65535]: T.30 T4 timer. Default: 3000.
v32_min_primary_rate [dword 0–33600]: This determines the minimum V.34 rate for
image data. This should be a multiple of 2400 and 0 allows the modem to decide the min rate.
Default: 9600.
v32_max_primary_rate [dword 0–33600]: This determines the maximum V.34 rate for
image data. This should be a multiple of 2400 and 0 allows the modem to decide the max rate.
Default: 33600.
v34_preferred_control_rate [dword 0/1200/2400]: This determines the maximum V.34
rate for the control data. This can be either 1200 or 2400 or 0. If 0, the modem decides which
control channel rate. Default: 1200.
cancel_receive_timeout_msecs [dword 0–65535]: If the modem has a large buffer, there
may be a long wait from the time of sending a CAN character (abort the receive) and the
modem's OK response. For such a modem, setting this timeout can speed the CANCEL process.
Default: 1000.
cancel_send_timeout_msecs [dword 0–65535]: If the modem has a large buffer, there may
be a long wait from the time of sending a DLE/ETX sequence (abort the send) and the modem's
OK response. For such a modem, setting this timeout can speed the hangup process. Default:
1000.
close_string_timeout_msecs [dword 0–65535]: How long to wait for response after sending
users close string if that string does not contain any '^' characters. Default: 5000.
command_timeout_msecs [dword 0–65535]: How long to wait for response for
miscellaneous commands such as ATE0V1, AT+FCLASS = 1 or AT&D2. Default: 1000.
