I am asked to use TAPI to dial a remote line that should then be used
for data communications by a device driver implementing a communications
protocol and using standard WIN NT serial device driver to do the hard
The trouble is that I can't find a way to leave the line open while
releasing it from TAPI so that the driver could open the serial device.
I have found documentation of LINEDEVCAPS member dwDevCapFlags that has
a bit called LINEDEVCAPFLAGS_CLOSEDROP that can be used to detect
whether lineClose will hangup the line.
I however have found no method how to influence that flag, that always
seems to have the wrong value for me.
Thanks in advance for any information un the subject
