Using a Fossil Driver with VBBS
The fossil driver can open up a whole new world to VBBS.
The "standard" serial driver which comes with VBBS is
not able to allow IRQ sharing between COM ports.
This is not so much a limitation in the serial driver, as it
is a limitation of the underlying operating environment.
A FOSSIL driver, on the other hand, can handle 2 or more
serial ports using the same IRQ line. In fact, a FOSSIL
can be used to control up to 8 ports. It can be "programmed"
to use almost any serial board in existance.
For the purposes of this document, we shall refer to the
X00 and BNU fossil drivers. If you're new to fossil drivers,
they are a "standard" way for programs to communicate with
serial ports, and you only need one installed on your system
in order to make use of it.
X00 is one type of fossil driver that loads thru CONFIG.SYS.
BNU is a another type of fossil driver that loads thru AUTOEXEC.BAT.
Both programs do roughyl the same thing, and yu have your choice of
which one you wish to use.
** Number of simultaneous open ports **
***************************************
The "basic" CONFIG.SYS install line for X00 looks like:
DEVICE=X00.SYS
The "basic" AUTOEXEC.BAT install line for BNU is:
BNU
By default, a fossil will assume you wish to have only
ONE COM port open at any given moment.
This doesnt specify WHICH port (COM1, COM2, COM3, etc),
but specifies the maximum number of simultaneous open
ports.
Each Port you request is like a "data channel," corresponding
to your VBBS data channels.
It is possible to request that the fossil make more ports
available to you.
For more detailed information on the driver, consult
the fossil documentation.
* VBBS Set Up *

Set up your VBBS Data Channels as you normally would.
