Lab 7-7 Parallel Port
Modes
Examine CMOS setup on your PC and
answer the following questions about your parallel port:
- Is there a parallel port coming directly off the system board?
- What modes are available for the parallel port?
- What is the currently selected mode?
- If the parallel port supports ECP, what DMA channels can be
selected for this mode?
- Write down the settings for this port below. Be sure to write down
ALL settings!
- Disable the parallel port using CMOS setup. Reboot the PC and
attempt to use the port by installing a local printer on LPT1 (you can do
this even if a printer isn’t really attached…just do the add printer
wizard) and then execute a print command to that printer. What happened?
- Reinstate
the original settings. Test to make sure the parallel port is working by
executing a print command once again.
- Remove
the printer you created.
