[Gumstix-users] Performing a serial timeout

[<ani...@pa...>]

Hi All,

I want to perform a serial timeout read through my gumstix ttyS2  
port.I use  normal read function but it
gets stuck up when the controller at other end doesnot respond to it  
or there is no physical connection between the two .

How can i give a read timeout option in C ?? I tried NON blocking  
option also but then i am not able to get data .

Suggetions are most welcomed.

Thanks in Advance

Anil
