Chapter 3: Software Installation - Windows NT 3-37
Echo User's Manual, ver. 0.00
Windows NT
Windows NT allows you to add up to 255 serial ports to your
computer system. The Windows NT serial port driver supports
IRQ sharing (if the hardware supports it) and the FIFO buffering
capabilities of the ST16C554.
Technical Tip
1. You can run under DOS the DOS programs porttest.exe and
portfind.exe to verify your settings and assure you have no
hardware conflicts. You will find these programs on the
DFlex DOS Driver diskette (p/n: DISK306).
2. If you did not receive a Windows driver diskette or you
require additional information, please go to the Download
Zone or the Knowledge Database in the Support Center on the
Connect Tech website for product manuals, installation
guides, device driver software and technical tips. If these
sources do not provide you with the help you need please
contact a Connect Tech Technical Support Representative
via email, telephone or fax for further information (numbers
and addresses are found inside the front cover of the
manual).
You can configure a single Echo serial adapter to share one IRQ
allowing that Echo’s serial ports to share one interrupt. You can
add as many Echo adapters as you have ISA slots for,
remembering that each board will need a unique range of I/O port
addresses and IRQ's.
Configuration
The following installation assumes that your computer system
comes with two standard serial ports, COM1 (at 3F8, IRQ 4);
COM2 (at 2F8, IRQ 3) and that you are installing an Echo
adapter.
1. You need to choose a range of I/O addresses for your Echo
adapter that will not conflict with any other addresses. A
good range to choose is the default settings, 280h, 288h,
290h, 298h, 2A0h, 2A8h, 2B0h, and 2B8h. Figure 16 shows
the example switch settings. Please refer to Figures 1, 2, or 3
in Chapter 1: Introduction for the location of the DIP
switch block SW1.
