2. Choose an IRQ for your Echo. It is possible to have the even
ports on one IRQ and the odd ports on a different IRQ, but
we recommend having all ports on one IRQ. Good choices of
IRQ's are 5, 10, 11, 12 and 15. The two serial ports that
come with your system usually use IRQ 4, 3 and LPT1 is
usually IRQ 7. Please refer to the Table showing typical IRQ
usage in Chapter 2: Hardware Installation. For our
example we will choose IRQ 10. Figure 15 shows the
example IRQ setting. Please refer to Figures 1, 2, or 3 in
Chapter 1: Introduction for the location of the jumper block
J1.

Technical Tip
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)
