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.
# 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.
graphics mode , the system sets the mode to graphics from text mode
#Configure terminal for configuration mode #exit for previous mode #ctrl+z for set up mode

ECP is faster (because it uses a DMA channel).
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.
Unidirectional mode or bidirectional mode. If using more modern standard ieee-1284, EPP or ECP Also, ECP & EPP
# 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.
If it's not compatible with your motherboard.
As much as possible keep the default setting of ECP; otherwise, you can also select an IRQ (interrupt request) line for the port.
ECP was designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
ECP mode.
we do not know every thing it means sheep's are weird
· Recall the ECP uses a DMA channel. Allow setup to keep DMA3 unless you suspect a conflict with another device trying to use DMA
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.
