Re: [bluetooth-dev] How to reduce 60 sec delay on Dial Up connection?
I believe the delay is due to the standard hangup sequence where the
Windows modem driver will send "+++" and "ATH" trying to receive any
confirmation of hangup.
You can try to install the attached *.inf file as a modem entry on top of
the virtual serial port. You may need the following entry in
connect "/usr/bin/chat -v '\r' '\r'"
Anycom Bluetooth software has a better solution. They associate direct
cable connection entries with the virtual serial ports. Then the modem
emulation of the OpenBT software should detect the direct cable chatting
sequence. Otherwise, this entry may help:
connect "/usr/bin/chat -v 'CLIENT' 'CLIENTSERVER'"

; 2) Go to the control panel and click "Modems"
