Attaching the ports on a PC
attach <hw_type> <io_addr> <vector> <mode> <label> <bufsize> <mtu>
[<speed>]
Configure and attach a hardware interface to the system. Detailed
instructions for each driver are in the Attach Commands chapter. An
easy way to obtain a summary of the parameters required for a given
device is to issue a partial attach command (e.g., attach asy). This
produces a message giving the complete command format.
<hw_type> is the kind of I/O device being attached to the
system.
<io_addr> is the base address of the control registers for the
device.
<vector> is the interrupt vector number. Both the address
and the vector must be in hexadecimal. You may put "0x" in
front of the numbers, but they will be interpreted in
hexadecimal even without the prefix.
<mode> controls how IP datagrams are to be encapsulated in
the device's link level protocol.
Choices are ax25 or slip.
slip Encapsulates IP datagrams directly in SLIP frames
without a link header. This is for operating point-to-point
lines and is compatible with 4.28BSD UNIX SLIP.
ax25 Similar to slip, except that an AX.25 header and a KISS
TNC control header are added to the front of the datagram before
SLIP encoding. Either UI (connectionless) or I (connection-
oriented) AX.25 frames can be used.
<label> defines the name by which the interface will be
known to various commands, such as "connect", "route",
"trace", etc.
<bufsize> For ASYNCHRONOUS PORTS, specifies the size of the
ring buffer in bytes to be statically allocated to the
receiver; incoming bursts larger than <bufsize> may cause data
to be lost.
For ETHERNET, specifies how many PACKETS may be queued in the
receive queue at one time. Excess packets will be discarded
as they are received. This is useful to prevent the system
from running out of memory should another node suddently
develop a case of diarrhea.
<mtu> is the Maximum Transmission Unit size in bytes. See
the System Configuration Manual for a discussion of the effect
of MTU on system performance.
attach asy <io_addr> <vector> <mode> <label> <bufsize> <mtu>
[<speed>]
Configure and attach a standard PC asynchronous I/O port using
the National 8250, 16450, or 16550 chip or equivalent to the system,
where:
<io_addr> is the comm port address; e.g., com1 = 0x3f8
<vector> is the comm port IRQ value.
attach axip <iface> <mtu> <ipaddress> [<callsign>]
Create a RFC1226 compatible AX.25 frame encapsulator for
transmission of AX.25 frames over the IP. This command is used to
establish a point-to-point AX.25 'tunnel' between two systems.
<iface> will be the name of the new interface,
<mtu> is the maximum transmission unit for the interface,
<ipaddress> is the address of the system on the other side of
the 'tunnel,
<callsign> is the optional AX.25 callsign this station is
listening on for frames to digipeat. Note that if you want
cross-tunnel digipeating to work, each attached axip interface
should listen to a different callsign. These should also be
different from other callsigns used on this station.
attach axip axip1 256 44.26.1.19 WG7J-15
attach pkiss <iface> <mtu> <ipaddress> [<callsign>]
Attach a serial port in G8BPQ polled kiss mode.
To attach other TNCs to be polled on the same port, attach them
as additional kiss devices (see below). They will automatically
be polled.
attach kiss <asy_iface_label> <port> <label> [mtu]
Attach a second kiss interface on the serial port. This command
allows the use of multiport TNCs.
<asy_iface_label> is the name of the serial port interface.
<port> is the port number (1-15) to use, and probably
should be 1. (the original asy port is automatically port 0 !)
<label> is the name for this second kiss port.
<mtu> is an optional mtu, if different from the mtu on the
first kiss port.
# Attach a dualport tnc in kiss mode.
# Ports are labelled 'port1' and 'port2'
# Attach a PC asynch port (com1 in this example)
attach asy 03f8 4 ax25 port1 512 256 9600
# Attach the second port on the multiport tnc
attach kiss port1 1 port2
attach netrom
This makes available a pseudo interface to enable NET/ROM
operations. This command is automatically executed when the netrom
server is started with the 'start netrom' command.
[ipaddress] is an optional ip address for the netrom interface.
If not set, the system 'ip address' will be used.
attach packet <softintr#> <iface_label> <maxqueue> <mtu>
Driver for use with separate software "packet drivers" which
conform to the FTP Software, Inc., Software Packet Driver
specification. See the Crynwr (TM) packet driver collection
if your hardware driver came without a packet driver.
attach scc
PE1CHL driver for generic 8530 cards
