Terminals, fonts, ESC codes, and why do I get all these funny characters: Terminal & Fonts

How to get a bigger textmode screen under Windows?

How to change codepage locally under Windows?

Physical Terminal (udev) problems

From http://bugs.freepascal.org/view.php?id=10758 :

There appears to be an additional wrinkle when using a user virtual terminal.
Symptoms: The User Screen overwrites the IDE screen.
Analysis: In ~/ide/fpusrscr.pas source code, in 'constructor TLinuxScreen.Init;', where FName = '/dev/vcsa/x'

TYFd:= fpOpen(FName, &666, O_RdWr);

always returns a '-1' due to the standard udev permissions for /dev/vcc/a* .
Brute force work-around: As root, chmod 666 /dev/vcc/a*" or edit /etc/udev/rules.d/50-udev.rules to make the permissions at boot:
original:
KERNEL=="vcsa[0-9]*", NAME="vcc/a%n", SYMLINK+="%k", GROUP="tty"
to:
KERNEL=="vcsa[0-9]*", NAME="vcc/a%n", SYMLINK+="%k", GROUP="tty", MODE="666"
Other: Maybe there is an underlying incompatibility between grab_vcsa and udev ?
