Once the computer has finished investigating the Modem's
Capabilities, you should see this screen. Port Information:
- Port: This is the name of the Communications Port
- Interrupt: Your computer has 16 interrupts. Each
interrupt can only be used by one device at any given time.
- Address: Like a memory address, this is the address
of the Communications Port in the system.
- UART: Acronym for Universal Asynchronous Receiver
Transmitter. This is the computer chip responsible for sending and receiving data through
your modem. The different UART types you will see are:
- NS8250 - Bad
- NS16450 - Bad
- NS16550 - Good
- If you have an 8250 or 16450 UART, you should approach your Computer
Supplier for an upgrade.
