    LPTx in PC vs port in Mach3, just need to clarify

    My computer has no parallel port on motherboard, so I bought a PCI parallel port board, and I set it as LPT2 in PC. While in Mach3, I clicked the port#1 and input the related LPT2 address. It works, anyway.

    Does it really matter if I set PCI as LPT1 or LPT3 or LPTx as long as I set port#1 with correct address?

    I tested with setting as LPT1 in PC, it works too. why?

    Thanks.

    LPT is just a name (alias) that software can use to call a port. It's like "Grandma's House" VS "238 West Oak St".
