Subject: NT serial connection solved !

HI
I posted a couple of days ago with a serial connection problem
on my work laptop AS 3.5/6 to NT 4.00 1381 sp6
I discovered the modem was on com1
I created com2 pushed the modem onto com2 rebooted and it worked
fine.
It seems that com1 must be dedicated to AS or it will not play.
Give it a go
Let me know how you get on
Cheers
Ric.

Hi Ric,
Interesting what you say about the modem being on COM1. I am not
at all technical, but have been confused as to why NT control
panel, ports, showed COM1 and COM2 when there is only one serial
port at the back of my laptop. It could well be that I have the
same problem.
Any chance you can expand on your "I created COM2, pushed the
modem to COM2 and rebooted"?? I understand the rebooting bit,
but not the rest of it!
Cheers,
Stewart

Hi Stewart
Go to Control Panel / Modems and see which port your modem uses.
Go to Control Panel / Ports and see how many ports you have
installed.
To get it all to work you MUST have activesync ONLY on COM 1. If
this means uninstalling your modem drivers and pushing them onto
COM2 then so be it. ( If you only have COM 1 installed install
COM 2 using default settings first, then uninstall modem then
reboot, then install modem drivers and push them on to COM 2 not
COM 1when prompted
The term COM ? refers to the drivers for a com port rather than
the actual number of physical ports you have on the machine. 1
com port can use up to 8 COM ? settings.
A bit confusing I know.
If you are still struggling let me know

I made a serial cable myself according to the pin layout as
described under Connectors on this website.
I use Active Sync 3.6 under NT4 and XP as well.
Unfortunately no connection was establised. From an XDA point of
view everything was OK and the XDA sends the word "CLIENT" to
the desktop PC. However the desktop PC did recognize this. And
so no answer was sent to the XDA.
I analysed the connection of a collegue of mine using an IPAQ
and official COMPQ serial cable. It turned out that in that
situation the DCD (Data Carrier Detect) signal was high. On a 9
pin COMport connector this pin 1.
According to the specification of xda-developers.com it should
not be used.
As a solution I connected on the 9 pin COMport connector pin 1
to pin 6. And now everything works fine!
I am happy, but how come nobody else discovered this???
