4.2.1 Command Line Options

To configure a QSP-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 QSP-200/300 must be inserted into for

this configuration argument to be used. socket must be in the range 0 - 15.

This option is always required.

Baddress specifies the base I/O address of the QSP-200/300 in hexadecimal and must

reside on an even 32-byte (20H) boundary. This option is required if the 'R'

option is not used.

Iirq specifies the interrupt level (IRQ) of the QSP-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

QSP-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.

Omode specifies RS-422/485 output driver mode. The QSP-200/300’s ports 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 ports are

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 16550. See the Hardware Information section for

more information.

H instructs the Enabler to enable the RTS-CTS modem control handshake.

When modem control handshaking in enabled, the 16C550 UART’s RTS and

CTS signals are connected to the RS-422/485 auxiliary channel (AuxOut and
