Cat made the screen permanently unreadable.
Kernel 126.96.36.199, Slackware 12.0
I have a file named juan34. I was sure it was a plain text file so, instead of running first 'file juan34' I directly did 'cat juan34'. The result was everything echoed to the console are the ascii caracters greater than 127 decimal. In other words, the screen is unreadable.
I typed 'exit' but this did not remedy the situation. The login prompt was written with these strange chars. In another console I'm running a program which I estimate will terminate execution in 20 hours or more, so I do not want to reboot the machine.
When I worked in MS-DOS, I had (made) a program that reinitialized the 6845 CRT controller, fixing this problem (for this could also happen under that O.S.). But, if there is a solution for MS-DOS, all the more so there must be one under unix/linux. Any help would be greatly appreciated.
