buflim
buflim specifies the maximum number of outgoing datagrams or packets to queue before starting
to discard datagrams. This mechanism is used to prevent the memory from filling up when a serial
link goes down.
bufsize
bufsize specifies the size of the ring buffer in bytes to be allocated to the receiver in raw mode.
intvec
intvec specifies the software interrupt number (vector) in hexadecimal to use for resident packet
drivers.
ioaddr
ioaddr is the I/O base address in hexadecimal of a serial port or the hardware controller and must
correspond with the jumper or switch settings used during the setup of the controller board. The
standard values for serial ports are:
COM1 03F8h
COM2 02F8h
COM3 03E8h
COM4 02E8h
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.
