[microblaze-uclinux] Serial input devices, serport.c

[pcolodron@xxxxxxxx]

Hello everybody,

I am planning to use input devices (mouse, touchscreen) over the RS232  
serial port of my XtremeDSP development kit.

To do this, I know I have to activate the option 'Input device  
support'-> 'Hardware I/O ports'->'Serial port line discipline'
as well as the driver of the device that I want to use.

However, I have tested my system and I realised that, in 'serport.c',  
the function 'serport_ldisc_read' is not called. I think that this is  
due to the fact that I did not define which tty device will be  
assigned to the new 'serio' device.

Does anybody know how to do this?

As far as I know, once the new 'serio' device is registered, the  
driver of the mouse or touchscreen will detect it and I could access  
to it in 'dev/input'.

Thanks in advance for your help.

Kind regards,

Pablo
