Manual

2. Installation Instructions

2.1. DOS Installation

The DOS installation procedure consists of 2 steps after the PCI Quad RS232 card is inserted:

1. Determining the resources that the PCI Quad RS232 has claimed.

2. Informing the Serial Solutions DOS device driver of those resources.

Determining PCI Multiport Resources

• Insert card into PC, as described in Chapter 2.

• Run BBCARDS.EXE, from the supplied CD by typing the following:

A:\ >BBCARDS

Where A:\ is the drive containing the supplied file.

BBCARDS will return a string that looks similar to the following (values contained in the string may

differ in individuals PC’s due to resource availability):

PCI Quad Users:

Card 1 is on bus 0, device 16, function 0

Card ID=2, revision 3: Quad RS232

Interrupt line 11 has been assigned

4 sets of 16550-compatible registers are at I/O address 0140

SISR is at I/O address 0104

Baud clock control is at I/O address 02d0

Write 0xf6 for /8 (default), 0xf2 for /4, 0xd6 for /2, 0xd2 for /1.

Note down IRQ, I/O address and SISR (the SISR is the Shared Interrupt Status Register, which is a read

only register which returns an index value that identifies which port on the card has an interrupt awaiting

servicing by the driver software.) In this case:

The IRQ = 11

The I/O address = 0140

The SISR = 0104

NEWCOM.SYS Parameters

The NewCOM.SYS device driver included with the PCI Quad RS232 driver software is used to set up the

card in DOS and has the following syntax:

NEWCOM.SYS /A port address, /L SISR, IRQ, range /B number buffer /S buffer /H Hardware Handshake

Where /A port address specifies COM number followed by a hexadecimal address in the form /Axy where x

is COM port range and y is I/O address.

/L SISR, IRQ, range specifies SISR address, card interrupt and COM port range. The COM port(s).

Range may be a single port OR a range of ports.

/B number buffer is used to set the number of pairs of buffers to be allocated to ports and is a

decimal number in the range 1-maxport.
