When might you need to disable ECP mode for parallel port?
An occasion when you need to disable the ECP mode for parallel port is when resource conflicts occur. In such a case, the EPP mode is the better option.
When might you need to disable ECP mode for a parallel port?
# If you are having problems with resource conflicts, you could try disabling ECP mode for the parallel port. EPP mode gives good results and does not tie up a DMA channel.
Why might you choose to use ECP mode for your parallel port rather than EPP mode?
ECP is faster (because it uses a DMA channel).
What might you need to disable ECP mode for parallel port?
If it's not compatible with your motherboard.
What are two possible settings in CMOS for parallel port mode?
Unidirectional mode or bidirectional mode. If using more modern standard ieee-1284, EPP or ECP Also, ECP & EPP
If ECP mode does not work on your parallel port what should you do next?
· Recall the ECP uses a DMA channel. Allow setup to keep DMA3 unless you suspect a conflict with another device trying to use DMA
Which parallel port standard uses a DMA channel?
Extended Capabilities Port (ECP) as designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
Which parallel port uses a dma channel?
ECP was designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
If ECP mode does not work on your parrell port what should you do next?
As much as possible keep the default setting of ECP; otherwise, you can also select an IRQ (interrupt request) line for the port.
What is ECP mode?
Short for Extended Capabilities Port, a parallel-port standard for PCs that supports bi-directional communication between the PC and attached devices(such as a printer). ECP is about 10 times faster than the older Centronics standard.
What are the different types of parallelism?
Standard parallel port (SPP), Enhanced parallel port (EPP), and Extended Capabilities port (ECP)
What are the different types of ports?
Standard parallel port (SPP), Enhanced parallel port (EPP), and Extended Capabilities port (ECP)
