SLIPPER and CSLIPPER Release 1.2
                --------------------------------

Slipper is a replacement for SLIP8250.  It provides a basic functionality
packet driver using the SLIP protocol.  It is written completely from scratch
using Turbo Pascal and Assembler.  Slipper has (hopefully) been designed for
high baud rate operation with standard non-fifo 8250 chips.  The 1.1 release
adds support for 16550 chips.  (FIFO trigger level 4 on receive)

Version 1.2 fixes some 16550 bugs and includes support for CSLIP.  Due to the
bulkiness of supporting cslip, there are two version of slipper provided.  The
standard version is call SLIPPER, and the CSLIP version is called CSLIPPER.
The command line parameters are the same for both versions.

Version 1.3 fixes some bugs in the CSLIP part, and does a slight
tidyup/speedup of some of the code and reduces stack requirements.  Also
added a handle for RARP packet types in the ether simulation.

Usage:   slipper [com<digit 1-4>] [vec=<hex vector>] [baud=<speed>] [ether] [?]

options (in any order):

        com<digit 1-4>   The serial comm ports 1 to 4.
                         com1      base=3f8, irq=4  (default)
                         com2      base=2f8, irq=3
                         com3      base=3e8, irq=4
                         com4      base=2e8, irq=3

        port=<hex port>  override the com port setting  (0000-FFFF)

        irq=<hex digit>  override the com irq setting  (0-F)

        vec=<hex vector> the packet driver interrupt vector
                         default is 60

        baud=<speed>     baud rate of the connection
                         default is the current speed setting.
                         max = 115200

        ether            simulate an ethernet board. (IP and ARP only)
                         default is non-ethernet

        ?                display the commands.

examples
        slipper

           - com1, vector=60H, baud=whatever defined, non-ethernet

        slipper com3 vec=63 baud=38400 ether

           - com3, vector=63H, baud=38400, ethernet simulation


also, you can type

    slipper ?

for the commands.
