LPT Forwarding on Windows hosts
Posted: 7. Dec 2012, 20:56
Hello all,
first of all, I know how to use search, but I could not find the information using search. I know there are a bunch of such threads.
Supposedly Virtualbox >= 4.2 supports parallel port forwarding for winblows host. The following is my setup:
Host:
OS: Windows XP x64
LPT: PCI Controller card @ non standard location, configured to be LPT1 (in the windows driver, was LPT3 when I installed the card)
CPU: Core i7 first gen (Nehalem), supports virtualization
Guest:
OS: Windows 2000
LPT using software: EETools MaxLoader, using some lib to ge direct port access and then directly accessing the I/O address (?) known to work under w2k.
LPT hardware:
EETools TopMax
What I did:
VboxManage modifyvm text --lptmode1 LPT1
VboxManage modifyvm text --lpt1 0x378 7
In w2k, the LPT port is detected, but still I have no communication between device & software. I assume it is the string given to --lptmode1 ? I tried with LPT1 and LPT1:
both don't work. do I need to use something like \\.\LPT1 ?
Also, could the root problem be that I changed the LPT number on the host? should I go back to LPT3?
Thanks for your help
