errors occurring. Setting this to lower than 19200 has the possibility that the UART
wont be able to keep up with the modem modulation throughput due to extra DLE escaped
characters. Default: 38400.
dtmf_detection_begin [string]: When the line_type is 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 format 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: 0.
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 OK. Default: 200.
enable_init_flow_control [boolean]: This is for the rare modems that return OK 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 init. Default: false.
get_receive_image_end_ok_timeout_msecs [dword 0–65535]: This is how long to wait
for an OK after receiving the DLE/ETX sequence that terminates a receive image. The modem
will receive the post page signal during this period. When the driver receives the OK, it will send
a +FDR and either start waiting for an image CONNECT if a MPS/EOP was received by the
modem or start waiting for a pre­phase OK because an EOM was received by the modem.
Default: 30000.
get_receive_image_start_connect_timeout_msecs [dword 0–65535]: This is how long to
wait for a CONNECT after sending +FDR. The modem will usually perform its training during this
period. If it returns an OK during this time the driver will assume it has reported a new DCS and
is stepping down its training rate. The driver will re­issue the FDR and restart this timeout. If a
modem steps through all training rates without returning new DCS/OK responses, this timeout
would need to be quite large to achieve connection. Smaller values will return control to the
application sooner when connections fail. Default: 60000.
get_receive_pre_phase_ok_timeout_msecs [dword 0–65535]: This is how long to wait for
an OK while in the initial pre­phase of a fax receive. When the driver receives an OK it will send
a +FDR. The modem usually exchanges TSI/CSI and DIS/DCS in this time period. Default:
35000.
get_send_image_start_connection_timeout_msecs [dword 0–65535]: This is how long
to wait for a CONNECT after sending +FDT to release the modem to send the TSI/DCS and
perform training. If the modem returns an OK the driver will assume it has received an FTT and
is stepping down to a new baud rate. The driver will re­issue the +FDT and restart this timeout.
If a modem steps through all training rates without returning new DCS/OK responses, this
timeout would need to be quite large to achieve connection. Smaller values will return control to
