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 underrun error because the modem drops carrier before all the page
datahasbeensent.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
modemandserialdriverbuffering.Default:200000.
slow_at_pause_msecs [dword 0–65535]: This is how many msecs to pause in the middle
and at the end of the "AT" for any command sent after a baud rate change. This gives the
modem time to auto baud and detect data/stop bit format before returning to its normal
commandinterpretingstate.Usethisforoldmodems.Default:100.
speaker_mode [string]: State of device’s speaker. This translates to an ATM# command.
Default:ON_UNTIL_CARRIER.
speaker_volume [string]: Volume of device’s speaker. This translates to an ATL# command.
Default:LOW.
stolen_port_restore_timeout_msecs [dword 0–65535]: This was used in Win 16 and DOS,
but probably does not have any application for when using TAPI in Win 32 since the Unimodem
driver is in control or modem reinitializes when an app is done using a port. When not using
TAPIinWin32,thereisnowaythattheportcanbestoleninthefirstplace.Default:1000.
wait_connect_xon_msecs [dword 0–65535]: How long to wait for the XON following the
CONNECT result code from the modem. If after this time period an XON is not received, the
driverwillstartstreamingimagedatatothemodem.Default:1000.
allowed_receive_baud_rates [string]: This setting restricts a modem to use only certain
baud rates. Use this to block a modem from using a rate or rates that it supports, but are
unreliable in your environment or are undesirable for some other reason. On transmitting, use
this as a mask; the modem will use only those rates you list. On receiving, set the fastest and
slowestrates;themodemwillallowthoseandanyinbetween.

Default:14400,12000,9600,7200,4800,2400.
allowed_send_baud_rates [string]: This setting restricts a modem to use only certain baud
rates. Use this to block a modem from using a rate or rates that it supports, but are unreliable
in your environment or are undesirable for some other reason. On transmitting, use this as a
mask; the modem will use only those rates you list. On receiving, set the fastest and slowest
rates;themodemwillallowthoseandanyinbetween.

Default:14400,12000,9600,7200,4800,2400.
carrier_wait [dword 0–255]: Seconds the driver to wait in the “dialing” or “answering” states
foracarrierfromtheremotedevicebeforehangingup.Default:45.
dial_wait [dword 0–255]: Seconds the driver to wait in the "ringing" state before hanging up.
Default:45.
flow_control [string]: Designates the type of flow control to use when sending data. If the
setting is XON_XOFF the driver observes XOFF signals when sending. The driver uses no flow
controlwhenreceiving.Format:EitherXON_XOFForRTS_LEVEL.Default:RTS_LEVEL.
