I need help with a PIC project that will convert standard RS232 serial data
from a PC to a custom serial protocol.
The custom serial protocol is: 1 start bit+ 16 data bits + 1 stop bit @
115200bps
The protocol is asynchronous and only requires half duplex.  Basically the
PC will send 16 bits of data then wait for a 16 bit response then send
another 16 bits and so on.  The side that transmits the custom protocol uses
1 line for transmit and receive and then 3 other lines for handshaking, so
that pin on the PIC would have to be set up for IN\OUT
I figure the only way this can be done is with bit-banging.  I have a 16F84
10mhz  and a 16F84 20mhz.  Does anyone think this can be done reliably with
the 10mhz? Can this be done with the 16F84 or do I need something bigger?

Thanks,
Louis
