Interrupt Level
   If your interrupt handler software is designed for chaining, it may share a level with another adapter, otherwise the selected level should be dedicated to the UCCTM-05 only. Interrupt level 3 (COM2:) can be shared, but is generally best avoided.
      <"Disabled">, 3, 5, 7, 9, 10, 11, 12, 15

Base Address
   Choose a base I/O address that does not conflict with another adapter. Setup allows you 16 possible choices although the UCCTM-05 is capable of 2048 I/O addresses (XXXX XXXX XXX0 0000B). If you need an address option that is not listed run GENADF.EXE. Setup will automatically warn you of any adapter I/O address conflicts
