6.4.1 BNU

         BNU, written by David Nugent, comes in two flavors. One is a
         device driver, similar to X00.SYS. The second flavor is a
         .COM file, loaded from AUTOEXEC.BAT or another batch file.
         The .COM flavor is assumed in the example. For a detailed
         description of the BNU driver, please refer to the
         documentation included in the BNU distribution archive.

         [AUTOEXEC.BAT]

         BNU /R=1024 /T=512 /L1:38400

         /R=1024     Specifies a receive buffer of 1024 bytes.

         /T=512      Specifies a transmit buffer of 512 bytes.

         /L1:38400   Locks COM2 at 38,400 BPS (for use with the 14,400
                     HST or HST/DS modems).

         If you are not using a high-speed modem the above example
         should most likely be modified to not lock COM2.
