ECP Half-duplex or Full-Duplex?

Discussion in 'A+ Certification' started by DigitalSierra, Oct 18, 2004.

  1. Hello, I was reading Faster, Smarter A+ by Drew Bird published 2004.
    He says that ECP is "2-way simultaneous Full Duplex..." while EPP is
    half-duplex. I've read other books that refer to ECP & EPP as both
    half-duplex.

    Does anyone know if ECP (Extended Capabilities Port) is full or half
    duplex?
    I hate it when my reference sources contradict each other.

    Thanks,
    DigitalSierra
