loadfont Utility

QNX Neutrino utility to load console text mode fonts (8x8, 8x14, 8x16).

Project for QNX Momentics IDE 4.6 included.

Using

Utility can be started from the boot script like this:

# Load Windows-1251 8x8 font to setup 50x80 text mode
loadfont /proc/boot/cp1251.08

# Run manager with disabled keyboard and only one console
devc-con -k -n 1 &

# Reinitialize the console
reopen /dev/con1

Additional tuning

Setting Locale

By default QNX uses UTF-8 encoding for strings at default locale "C" (LC_TYPE="C"). To enable using of any other code pages (for example Windows-1251) symbols locale must be set to "C-TRADITIONAL" by setlocale function:

setlocale( LC_CTYPE, "C-TRADITIONAL" );

Setting character set

Also a simple VGA console and keyboard I/O manager devc-con after reopening console resets high half of ASCII table named "GR" (Graphics Right) to the default "G2" and "ISO-Latin1 Supplemental". It must be restored back to the "PC Character Set" using console Esc-sequences "Esc }" and "Esc * U":

printf( "\x1b}\x1b*U" );
