Writing data during * data phase is known to be broken (due to requirements of two byte writes). * Removing "Phase" debug messages. * * PS: Took four hours of coding after I bought a drive. * ANZAC Day (Aus "War Veterans Holiday") 25Apr98 [ 0.14 ] * * Ten minutes later after a few fixes.... (LITERALLY!!!) * Have mounted disk, copied file, dismounted disk, remount disk, diff file * ----- It actually works!!! ----- * 25Apr98 [ 0.15 ] * * Twenty minutes of mucking around, rearanged the IEEE negotiate mechanism. * Now have byte mode working (only EPP and ECP to go now... :=) * 26Apr98 [ 0.16 ] * * Thirty minutes of further coding results in EPP working on my machine. * 27Apr98 [ 0.17 ] * * Due to work commitments and inability to get a "true" ECP mode functioning * I have decided to code the parport support into imm. * 09Jun98 [ 0.18 ] * * Driver is now out of beta testing. * Support for parport has been added. * Now distributed with the ppa driver. * 12Jun98 [ 2.00 ] * * Err..
