Hi all,Once the card is inserted or removed, an interrupt is generated on the serial device ( which is a UART Chip, in my case ) and the interrupt handler sends a SIGIO signal to the application. On receiving the signal, the application can read and determine whether card is inserted.may i ask you 2 questions ?
1. I want to check whether the card is inserted (so exists in reader) or
removed (sp doesnt exist in reader). Is it necessary to write a daemon
that monitoring the reader by using CT_init periodically ? I guess this
will make system so busy. Any idea? How to know when the card is inserted?
Also, in my case, the reader sends a sequence of bytes, which will tell the application whether the card is inserted or removed.
I guess, U'll have to use interrupts, polling
eats up lots of CPU cycles .
2. Im doing LTSP and smartcard. I have posted it before. I got very
confused. The main problem is: the LTSP is run at the server, and my
reader is plugged at the client side. How can the server know whether the
card is inserted or removed.Any idea ? please help me if you know something.
