Re: Using a dos program that detects a signal on the parallel port

You might have to enable either direct I/O port access and/or IRQ 
passing in the dosemu.conf file by un-commenting and editing the setting:

$_ports = $_ports, " device /dev/lp0 range 0x378 0x37a"
$_irqpassing = "7"

You will need to run it with -s to give direct hardware access (with 
sudo for root privileges) in such a case.

I think the normal IRQ is 7 for the parallel port, and 5 for a 2nd 
parallel port (if fitted), though 5 is also used by the old sound card 
(if used/emulated).
