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
