Error while reading COM2

I am using PB 4.2 and pxa255 board.

When I am trying to load 'bthuart.dll' but it is giving error while reading
on COM2.

"4294793688 PID:83c7c61e TID:839f4b8e Error reading COM port: GetLastError =
0x00000006 (6)"


The registry entry for serial is:
-----------------------------------
HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial1]
"Dll"="xsc1bd_serial.Dll"
"IoBase"=dword:a6400000 ;BTUART_BASE_U_VIRTUAL
"Irq"=dword:0 ;22 - Dummy value. This subkey is not really used by the
driver.
"Tsp"="Unimodem.dll"
"IoLen"=dword:24
"DeviceArrayIndex"=dword:2
"Prefix"="COM"
"Index"=dword:3
"Order"=dword:0
;"Priority256"=dword:67 ; Using default priority value
"DeviceType"=dword:0
"FriendlyName"=LOC_FRIENDLYNAME_SERIAL2
; Eliminate flow control bit
"DevConfig"=hex:
10,00,00,00,05,00,00,00,10,01,00,00,00,4B,00,00,00,00,08,00,00,00,00,00,00
"Is485"=dword:1
"RTSDelay"=dword:500

Can anyone tell me wat should i do???

Well, look up error 6 first. It's "The handle is invalid." according to the
eVC Error Lookup tool. At a guess, I'd say that there isn't a serial port,
COMn:, corresponding to whatever you're telling bthuart.dll to use (or
something along those lines). Verify, first of all, that in
HKLM/Drivers/Active, you see the serial port name that you're trying to use.
It would be worthwhile to look back through the serial debug messages, too,
as it seems unlikely to me that the error code given there would be the
first indication of a problem.

There is entry for COM2 in HKLM/Drivers/Active.
Moreover the same setting works fine in PB 5.0.
