Kirk, I like your idea but I got lucky and didn't need to use it.
I guess I was not real clear on what I was asking. I knew that the ports in the manual were wrong and the correct ports were the ones from the "lspci -v". My problem was the fact that the example "lspci -v" from the wiki and the one from the manual both showed a list of port numbers increasing down and both showed the port at the top of the list to be a valid port (i.e., the lowest port address), while my result had the highest address at the top of the list. Anyway I took a gamble, and used the "0xec00" in my ".hal" file, plugged my cable in to one of the two new ports, and got lucky on the first try. Everything worked. Actually it wasn't the first try, I had tried, loadrt hal_parport cfg="0xec00 0x378" and it hadn't worked so I changed it to loadrt hal_parport cfg="0xec00" and it worked. I had tried the whole list of ports on both connectors without any luck when I had left the 0x378 in the config statement as the second port (without adding the necessary reads and writes). Can anyone explain why that won't work? And what does the "1" or "-1" after the read or write command mean? Alan --- Alan Condit 1085 Tierra Ct.

Usually, pin 1 port zero is assigned to something else, so I comment the line out and put the new one in. Then I set the "loadrt hal_parport cfg="0xXXXX"" line to load only one port and put in the "addf parport.0.read servo-thread" and "addf parport.0.write servo-thread". I start with 0xXXXX being the first address on the lspci -v list. I bring up EMC2 with a voltmeter on pin 1 (and to ground, pin 18 through 25, or connector shell) of a PCI parallel port and with AXIS, toggle Flood. I check each pin one for a toggling voltage. If the first address doesn't work, I exit EMC2, edit the .hal file for the next address and try again until I find the address for each parport. Sometimes I can find the addresses right away, sometimes I mess up the configuration and have to go through the procedure a couple of times to correct my mistakes, but so far this method has eventually worked. I also have a habit of not remembering to enter an "addf hal_parport.X.read/write" for each address in the final .hal file.
