Is it possible to add an option to forward this "blocking call"
to the smartcard readers' driver?
I'm about to write a driver for the Intertex readers, and they can signal
a status change by sending two characters over the serial line.
I'm too new to this to tell the best implementation, but I guess a new (?)
CT-API command will do. (CT_Data() probably needs to be reentrant then.)
GetStatusChange() calls it:
If supported, it waits for the reader and returns at status change.
If "unknown command" is returned, there is no support from the reader,
and you have to loop instead.
Or a new CT_GetStatusChange() maybe? But this breaks backward compa-
tibility with all of the current drivers.
Thanks
