PCD
Parameters: value is an 8 bit int with each bit representing a bit of the I/O port.
Returns:
Function:
undefined
These functions allow the I/O port direction (TRI-State) registers to be set. This
must be used with FAST_IO and when I/O ports are accessed as memory such as
when a # BYTE directive is used to access an I/O port. Using the default standard
I/O the built in functions set the I/O direction automatically.
Each bit in the value represents one pin. A 1 indicates the pin is input and a 0
indicates it is output.
Availability: All devices (however not all devices have all I/O ports)

set_uart_speed( )
Syntax:
set_uart_speed ( baud , [ stream, clock ])
Parameters: baud is a constant representing the number of bits per second.
stream is an optional stream identifier.
clock is an optional parameter to indicate what the current clock is if it is different
from the #use delay value
Returns:
Function:
256
undefined
Changes the baud rate of the built-in hardware RS232 serial port at run-time.
