- What kind of a comment do you want? PCMCIA cards have access mediated
- via card.resource and software interrupts are attached to indicate when
- various conditions occur on the card.
-
- Data is read from a memory-mapped I/O location until a status flag
- indicates that there is no more data to be read, or until the MTU
- of the unit has been reached.
-
- I don't know what you mean with your comment about a serial port.
