Hi all,

I am developing an application where I need to check the availability
of Bluetooth and IRDA support on my Windows Mobile 5.0 smartphone
device.

As I could c there is an API "BthGetHardwareStatus" to get the
availability/status of Bluetooth hardware. But I am not able to find
the same for IRDA.
Do we have the same type of API for IRDA availability/status checking?

I'm surprised you have had only one answer. I'll at least attempt to
help.

I use IR as a COM port. I detect support by looking for the Index
value in
HKLM\Drivers\\BuiltIn\\IrCOMM
If I find that, I convert it to the port:
1 -> COM1:
2 -> COM2:
etc.

Here are comments from my code that include references:

I even need to get the notification for the change of status[on/off] of
these devices. Is it possible to get any callback for these hardware
status change.

Thanks in advance.

Raj
