Other PDP11 simulators

Rumor has it that Ron Hudson may have mentioned these words:

Did you try rerouting the output thru what's called a FIFO? It's similar to 
a pipe (|) from the command line, but it's linked into the filesystem. The 
only caveat that I remember (I've not used them much) is they're only one 
way, so you'll need two pipes for 2-way communication. Gee, think you could 
spare a couple of inodes??? ;-P

Here's a good page about 'em:

Googling for "linux FIFO" brings many others... ;-)

Isn't there a way to re-route the serial port to 'console' invisibly in 
Linux? I *thought* there was, but I've never done it...

Maybe this would help...

Anyway, I hope it helps, but I've never run simh, so I don't know the 
particulars of it...

Laterz!
