Re: Remote control of Dosemu

[Richard <R.Gregory@liverpool.ac.uk>]

Hi John,

I had this problem when running Norton Ghost, it asked a question at 
startup that needed the sequence <Tab><Tab><Enter> before proceeding 
with the command line options. The available DosEmu options didn't work, 
so I wrote a kernel module that simulated key presses. This was for a 
2.4 kernel and a hack, I'm no kernel hacker.

In my case Ghost was running in a console on the front display. To get 
an idea of Ghosts progress, I found the memory at 0xA0000 showed a 
cross-section of the 4 colour screen. It looked like it was interlaced, 
though I couldn't figure out how. For my purposes it was enough to save 
the screen. It is possible the text version is also available in a 
constant memory location.

The details of the kernel module and screen grab are here, in section 5:
