Quatech DSP-200/300 - Manual (Page 14)

2.2.1 Command Line Options
To configure a DSP-200/300 in the system, the Enabler requires one command line argument
from the user to determine the configuration of the card. This argument must be enclosed in
parenthesis and within the argument, any or all of the following parameters may be specified
using a comma (no spaces) to separate each parameter:
Ssocket specifies which PCMCIA socket the DSP-200/300 must be inserted into for this
configuration argument to be used. socket must be in the range 0 - 15. This option is
required if the 'R' option is not used.
Baddress specifies the base I/O address of the DSP-200/300 in hexadecimal. This address
must reside on an even 8-byte boundary. This option is required if the 'R' option is
not used.
Iirq specifies the interrupt level (IRQ) of the DSP-200/300 in decimal. irq must be one
of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired.
This option is required if the 'R' option is not used.
Waddress specifies the base address of the memory window required to configure the
DSP-200/300. Set address = D0 for a memory window at segment D000, address =
D8 for a memory window at segment D800, etc. Valid settings for address are C8,
CC, D0, D4, D8, and DC. If this option is omitted, a memory window at segment
D000 will be used.
Odriver specifies RS-422/485 output driver enable option for theDSP-200/300. The
DSP-200/300’s port may be configured for either full duplex or half duplex
operation with this option. If this option is omitted, the default setting is the
RS-422/485 port is configured for full duplex operation with the RS-422/485 output
drivers always enabled. In half duplex mode, the RS-422/485 transmitter may be
enabled and disabled via the RTS (request to send) or DTR (data terminal ready)
signals. Both RTS and DTR are controlled through the Modem Control Register of
the 16750. See the Hardware Information section for more information.
