Subject: After flash,where did COM1 go?
From: reswobslc
Date: 29 Dec, 2002 03:04:06
Hello,
I have a weird issue that came up on my T-Mobile PPCPE after I
flashed from 3.02 to 3.14. I can no longer open COM1, in
anything!
I can't open COM1 in Pocket Streets (it doesn't even show up in
the COM port list).
If I load a terminal emulation program, it sees COM1, but when
trying to open the port, it fails.
There is no equivalent replacement port for it. Other COM ports
are COM2, COM3, COM8, COM9, but all of these have different
documented purposes and aren't my GPS com port.
Anyone have any ideas?
Mike

Just to make sure my own software didn't cause problems, I
backed up my RAM to SD and hard-reset my phone. COM1 still
didn't come back... however...
I was able to answer my own question by finding the following
answer in a newsgroup:
------------
You have to change a registry value:
HKLM\Comm\Irsir1\Parms
change the value "Port" from 1 to 9 and then reset your device.
Now you can use your GPS on com1 without compromising others
phone functions.
-------------
After having done this, COM1 is back, now COM9 is gone. I will
say this solved my problem, though if anyone tries this and
finds unexpected problems resulting from COM9 being gone (and
comes up with a better idea of which number instead of 9 would
be more appropriate), definitely say something!
ADMIN please post this fix somewhere as surely others will have
the same issue!

I have (almost) the same problem. When I start TomTom Navigator
I get the fault: Cannot open COM1: Port does not exist. When I
alter the value from 1 to 9 all goes well with TTN. However I
then will be not able to make a GPRS connection (when the value
is 1 then I can).
Please help.
TIA,
Jeffrey

I had exactly the same problem with TomTom routeplanner but if
you turn off the Infra Red Receiving option under
Start/settings/connections/beam I think you will find that com1
then becomes available. I also turned of the 'Enable
synchronisation when cradled using:' in the Active Sync options
as I had a feeling that the XDA detected the seial connection
and was trying to sync. with my GPS. I alson found that if you
disconnect the cable when navigating that it locks the XDA up
which then has to be reset.
