I am trying to install the Debia 3CX Iso on a machine without graphic Card over serial terminal emulator.
After i use any Install Option from the Iso I get the error
undefined video mode number: 314
Is there a way to solve this problem?

got it fixed. had to set vga=788 to vga=288 and add "console=ttyS0,115200n8" at the end.
