[ct-user] CT-MFJ 434

[John Bednar]

I have one laptop where the BIOS text setting is likely incorrect
because the CT LPT port keying only works in one of the
BI-Directional modes. 

Word to the wise, try all the BIOS LPT port settings if the
AT-Compatible mode doesn't work. Remember to cycle through all the
messages and then connect the LPT connector. My interface gets
confused if the LPT pins are not in the correct starting state.

As someone stated, you may have to change the BIOS to set the
correct type of parallel port.  Also, I noted that the LPT port
pinout on the k1ea website says that pin 11 is ground.  I looked at
it the other day and it wasn't.  Maybe one version of the software
sets or resets that bit to ground and one doesn't.  If your
interface uses pin 11, you might want to switch to some other ground
pin, such as 18.
