baycomepp: Baycom EPP modem driver

NAME

baycomepp - Baycom EPP modem driver

SYNOPSIS

baycomepp [ -lknvcaz ] [-p portaddr] [-m modestr] [--epp] [--ecp] [--eppconv] [--eppafsk] [--ifname name] [--hwaddr callsign] [--ipaddr ipaddress] [--netmask netmask] [--broadcast broadcast]
DESCRIPTION
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).
OPTIONS
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

FIRMWARE OPTIONS

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
