1. You should review the sample Irda NDIS miniport driver Irsir in
public\common\oak\drivers\irmac\irsir. It uses the Win32 serial API
functions to access the underlying serial port. The only hardware specific
bit of code in it is the part that changes the baud rate. Esi.c has
functions specific to the Extended Systems Irda dongle. You could replace
those with functions for setting the baud rate of your device, if your Irda
dongle is external. If your Irda dongle is not external, then SetCommState
is enough to change the baud rate and you don't need to worry about
changing any code; you can probably use Irsir as is.
2. A dongle is an Irda transceiver. Irsir is written such that it can
control an external Irda dongle attached to the 9-pin serial port or use an
internal dongle. An internal Irda dongle is integrated into the hardware.
It sounds like you have an internal dongle.
3. see above.

| Hi,
| We are developing IRDA driver. Actually in our board WINBOND W83977F
| is controlling I/O device and IrDA sensor part number is HSDL-3610. Since
| this is supporting SIR, we are trying to develop SIR driver for this. In
| that i have following doubts,
|
| 1. For SIR, there no need to access any of the hardware registers (like
| SELBANKEN set0) in the W83977 ? basically all the sampe code we had seen ,
| no where we had seen the codes related to hardware specific or hardware
| specific registers.
|
| 2. What is the meaning of dongle?
|
| 3. What is the difference between Internal IR or External dongle.
|
|
| Can help me out in this issues ?
|
| Waiting for your reply,
|
| Thanks in Advance,
|
| R.Ravindran
