iovec
iovec is the hardware interrupt vector used by the serial port or controller and must correspond
with the jumper or switch settings used during setup of the controller. The standard values for
serial ports are:
COM1 4
COM2 3
COM3 4
COM4 3
irq
irq is the hardware interrupt vector used by the network interface controller. This is only used for
faster response in Sockets.
modemfile
A file containing the modem commands and scripts.
speed
speed specifies the transmission speed for serial interface devices (baud rate). Before using a
serial connection you have to set flow control with the param command.
Examples
interface pdr if0 dix 1500 5 0x60
interface asy ser0 cslip 576 15 0x3f8 4 9600
interface asy p0 ppp 1500 30 0x3f8 4 9600 pppmod.mod
ip
ip displays or sets the values of the options selected when defining the IP (internet protocol) host
address of the next interface to be defined.
Syntax
ip address [hostid [/net_bits] ]
ip status
ip ttl [number]
ip address sets the IP host address of the next interface to be defined. A route is automatically
added to each interface for the default or specified net mask for its address. To make an automatic
route the default, specify the net bits as zero. When specified without the optional parameters, ip
address displays the current value(s) of the local host IP address(es). To assign different IP
addresses to different interfaces on the same host, an ip address statement must precede each
interface definition. The last IP address given is used in case of missing ip address statements.
ip status displays Internet Protocol (IP) statistics, such as total packet counts and error counters of
various types. It also displays statistics on the Internet Control Message Protocol (ICMP). This
includes the number of ICMP messages of each type sent or received.
ip ttl sets the default time-to-live value which is placed in each outgoing IP datagram. The ttl
value limits the number of gateway hops the datagram is allowed to take in order to kill datagrams
that got stuck in loops.
