                      FOSSIL dirver setup information
-------------------------------------------------------------------------------


The following is the setup for the two most common FOSSIL drivers for the 
USR high speed modem line (9600+).  This includes both Courier and Sportster 
modems.


Because the majority of BBS software out on the market today requires that you
have a FOSSIL driver loaded in order to operate the BBS software.
If the driver is NOT loaded, then you will not get a response from the modem,
making it look like the modem is not functional. Also if the driver is
installed, but installed incorrectly (for example locking the baud rate in the
FOSSIL at a different rate than in the BBS software), then you will get garbage
on the screen, making it look like the modem is at fault again. It takes about
90 seconds to verify their FOSSIL driver setup which could save hours of
troubleshooting on the backend.

                    X00 setup:  (up to and including v1.50)
-------------------------------------------------------------------------------
In CONFIG.SYS:

devicehigh=c:\x00.sys E 1 B,0,19200 F=15 T=2048 R=2048

E = Eliminate startup message
1 = Allocate for one port (adjust as needed)
B,0,19200 = Lock port 0 (COM1) at 19200 (adjust as needed - use 1 for COM2) 
F=15 = FIFO threshold set to 15 bytes before dumping (only for internals
       or for those who have 16550 on their serial card)
       NOTE: Running this threshold at 15  leaves no room for interrupt
       latency due to slow hardware or excessive TSR's.  It would be a little
       more conservative and run this at about 8 or so.
T=2048, R=2048 = Transmit and Receive buffers set to 2k each.



-------------------------------------------------------------------------------
   BNU setup (up to and including v1.88, do -NOT- use v1.89, has fatal bugs)
-------------------------------------------------------------------------------

In CONFIG.SYS:

devicehigh=c:\bnu.exe /M- /F /L0:19200 /R=2048 /T=2048 /Z

In AUTOEXEC.BAT:

lh c:\bnu.exe /M- /F /L0:19200 /R=2048 /T=2048 /Z

/M- = Disables startup message
/F = provide fast ANSI interpretation
/L0:19200 = Lock port 0 (COM1) at 19200 (adjust as needed - use 1 for COM2) 
/R=2048,/T=2048 = Transmit and Receive buffers set to 2k each
/Z = enable 16550 FIFO buffer (only on internals or those with 16550 UARTs
        on their serial cards)
