This is code for a SmartCard - not commented

RB4 connect to SDA of memory (24LC16)
RB5 connect to SCK of memory
RB6 connect to OSC1 of Pic16F84A and Smartcard pad
RB7 connect to SmartCard I/O pad
RESET connect to SmartCard Reset pad

MPLab also dont like the use of this instruction - "Not recomended'

I try to get behind the basics for a Hotel Management/Access system. The
timing routines (9600 baud) and read/write to memory routines.

This code read/save data from the memory chip, and send/receive data from a
SmartCard reader/writer

The Write/Read routines change the PortB I/O directions as needed. I suspect
that the port state is not that "important" at initial startup...
