Edit /etc/ttytab to achieve this. Additionally, you may want to adjust
NR_CONS in /usr/src/include/minix/config.h and re-compile.

With kind regards,

Rather console and ttyc1 to ttyc3

In addition, please keep in mind that the MINIX console uses a design
compatible with EGA, which means the total space for the buffers is
limited to 32KB (addresses from 0xB8000 to 0xBFFFF); keeping in mind
that each character on screen counts as two bytes, a 80x25 console needs
4KB, and four 80x50 consoles need 32 KB, and this is no surprise.

Also by default, only the devices until ttyc3 are created; if you
increase NR_CONS, you will have to create the relevant devices,
# cd /dev && MAKEDEV ttyc4


Actually untested claims, error reports are welcome.
