NOTE: If you need to specify a non-standard port address and IRQ, then 
the syntax is PORT:AAAA:X where AAAA is the base address and X is the IRQ. 

PORT is optional, and PROWORDS will default to standard addresses and irq's
if PORT is not used. PROWORDS will assume COM1 = 03F8 IRQ 4, COM2 = 02E8 
IRQ3, COM3 = 03E8 IRQ4 and COM4 = 02E8 IRQ 3.  If you have a different 
non-standard port address and irq, you would then use the PORT cmd to change
the defaults. 

Below is some examples of how PROWORDS could be called up Notice PORT is always
the second or third (last) argument on the commandline. 

    ie...

    PROWORDS  PCBOARD.SYS  PORT:xxxx:a

PROWORDS also supports the use of FOSSIL drivers.  The syntax for a FOSSIL
driver is: PORT:F:P. The 'F' tells PROWORDS to use a Fossil driver for it's
communications.  The 'P' following it tells it which port to use for the
Fossil. Example - PORT:F:1, tells PROWORDS to use a fossil driver for port 1.

Digiboard Intelligent Async boards are  supported thru the Universal
DOS driver for Digiboard.  The syntax is the same as the Fossil driver
except you replace the F with D and give the channel number to use.
Example - PORT:D:6 tells PROWORDS that it is connected to a Digiboard and 
to use channel 6 on the Digiboard.


EXAMPLES: 

ProWords  Pcboard.sys                    ;Using standard ports
ProWords  Pcboard.sys PORT:03E8:5        ;Using non-standard port
ProWords  Pcboard.sys PORT:F:1           ;Using a fossil driver on port 1
ProWords  Pcboard.sys PORT:D:5           ;Using Digiboard channel 5
