Chapter 3: Software Installation - QNX 2.XX 3-11
Echo User's Manual, ver. 0.00
QNX 2.XX
When installing Echo boards under the QNX 2.XX operating
system, it is important to note the following:
Note:
1. After booting, QNX looks for serial ports at the following
addresses: 3F8, 2F8, 280, 288, 290, 2A0, 2A8, 2B0, 2B8,
3E8, 2E8 hex.
2. If QNX finds ports at these addresses, QNX assigns the
names $tty3 ($mdm), $tty4 ($term1), etc.
Technical Tip: You can use
osconfig to alter or add to these
addresses.
Configuration
Many computers include both COM1 and COM2 directly on the
motherboard. With this in mind, check your computer to see if it
has either or both of these ports as standard equipment or as
options. To avoid possible conficts with COM1 and COM2,
Figure 6 describes a recommended DIP switch setting for port
addresses. See Figures 1, 2, and 3 in Chapter 1: Introduction
for the location of switch block SW1.
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 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).
