I use X00.SYS Fossil Driver and loaded in my CONFIG.SYS, if you need to load
your fossil driver in your AUTOEXEC.BAT then rename the X00.SYS to X00.EXE.


Use the following command line in your CONFIG.SYS if you have 2 High Speed
Modems attached to COM1 and COM2 respectively and to lock your fossil and 
modems at 19200. If you have been locking your board and fossil driver higher
then please replace the 19200 with your correct value

DEVICE=X00.SYS E 2 B,0,19200 F=15 T=512 R=1024 B,1,19200 F=15 T=512 R=1024

Use the following command line in your CONFIG.SYS if you have 1 High Speed
Modems attached to COM1 and to lock your fossil & modem at 19200.
If you have been locking your board and fossil driver higher then please 
replace the 19200 with your correct value

DEVICE=X00.SYS E 1 B,0,19200 F=15 T=512 R=1024 

Use the following command line in your CONFIG.SYS if you have 1 High Speed
Modems attached to COM2 and to lock your fossil & modem at 19200.
If you have been locking your board and fossil driver higher then please 
replace the 19200 with your correct value

DEVICE=X00.SYS E 1 B,1,19200 F=15 T=512 R=1024

If you are only using a 2400 baud Modem then your command line will just be
simply the following:

DEVICE=X00.SYS E

If you are only using two 2400 baud Modems in COM1 and COM2 respectively then
your command line will just be simply the following:

DEVICE=X00.SYS E 2

Note: Please look in your X00 Fossil Driver Documentation for more details.
      X00.SYS and X00.EXE is a product of Ray Gwinn


Also if you are or will be using BNU Fossil driver, then look in the BNU
documentation for the proper command line, as i have never used BNU 
personally. Use the one that best worked for you.
