BaycomEPP 0.2                                      13 May 1998                                      BAYCOMEPP(8)

baycomepp  is  a user mode driver for the Baycom EPP modem family. It currently supports the conventional
       EPP modem (using the IDT 72xxx FIFO's) and the FPGA (Xilinx  XCS10)  variant.  The  driver  automatically
       initializes  the  FPGA  modem  depending  on  the  requested  mode.  In order to keep the resident memory
       footprint small (approx 20kBytes plus standard system shared libraries  like  libc),  the  initialization
       code  is  contained in a shared library called baycomfpga_init.so.  This driver is able to automatically
       attach itself to the kernel network stack as a network interface (usually called  ax0).  To  do  this  it
       requires the Linux Kernel MKISS driver (enable CONFIG_MKISS).

intclk uses FPGA internal clock; don't use if an external oscillator is on board.

       extclk uses  the  external oscillator; recommended if the internal modem is used, as the frequency of the
              FPGA oscillator is not accurate enough.

       intmodem
              uses the internal modem

       extmodem
              uses a DF9IC type modem connected to the high speed modem connector

       divider=x
              sets the clock divider for the internal modem (baud=fquartz/16/divider)

       loopback
              sets an internal modem loopback

       extstat
              allows extended status readback

       noextstat
              disallows extended status readback

baycomepp accepts the following options:

       -h--help Display an overview of the available command line parameters and exit.

       -v--verbose Increases the verbosity of the output. May be cumulated.

       -p--port  Specifies  the  base  address  of  the  EPP  capable  parallel  port to which the modem is
              connected. Use the 0x prefix to specify hexadecimal numbers.

       -m--mode Specifies various ``firmware'' options.

       -n--no-daemon Do not start up in background as a daemon. Also log received and  transmitted  packets
              to stdout.

       -l--log Log to syslog.

       -k--kill Kill running baycomepp daemons. Don't start the driver proper.

       --epp  Start up in EPP FSK mode. Requires the FPGA version.

       --eppafsk
              Start up in EPP AFSK mode. Requires the FPGA version.

       --ecp  Start up in ECP FSK mode. Requires the FPGA version.

       --eppconv
              Start up in conventional EPP FSK mode. Requires the conventional version.

       --ifname
              Set the name of the interface (requires Linux 2.2.x)

       --hwaddr
              Set the hardware address (callsign) of the interface

       --ipaddr
              Set the ip address of the interface

       --netmask
              Set the netmask of the interface

       --broadcast
              Set the broadcast address of the interface
