Question:
How do you install it under Windows 95?
Answer:
You must install the special HPC communications port first. This is the key to installation.
1. Go to Add new Hardware (do not let Windows 95 search your Hardware.)
2. In the Hardware type menu select "ports (com & lpt)".
3. Then click on "Have Disk".
4. Then point it to the ISA HPC modem diskette.
5. Win 95 will assign I/O and other resources..
6. Then click next and then finish.
Then for the modem it is basically the same thing except that you select modems in the Hardware type menu.
