Unfortunately, that's roughly the same as asking "How do you talk to 
an ethernet device". You have to know the higher level protocol that 
this device uses. E.g. most "dial-up" type modems use "AT" protocol 
to initiate calls. I don't know if there is a standard protocol in 
the world of SIM card readers. If they're vendor specific then you 
might need to get the documentation for this device.

Once you know what has to be sent and received to talk to the reader, 
I may be able to help with configuring the port and communicating 
with the device. You would treat ttyUSB0 the same as a real serial 
port, such as ttyS0.
