Note

All Echo ports interrupt on Channel A, IRQ 10.

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)

3. You can now install the Echo in your system and start up

Windows NT. Once Windows NT has started, logon as

administrator (installation specific account).

4. For Windows NT 3.51 open the

MAIN PROGRAM group. For

Windows NT 4.0 select the START menu and SETTINGS.

5. Click on the

CONTROL PANEL group.

6. Click on the

PORTS group.

7. Click the

ADD button.

8. Set the desired

COM PORT NUMBER if necessary. This number

will default to next available

COM PORT NUMBER, in this case 3

since the system has standard serial ports at COM1 and

COM2.

9. Set the

BASE I/O PORT ADDRESS by entering the port address

for the Echo’s first serial port, in this case 280.

10. Set the

INTERRUPT REQUEST LINE (IRQ) for your Echo adapter

by selecting a number from the list, in this case 10.
