What's the difference. I'm asking because i have problem as below when using real serial console (PCengines apu). I have TERM set to xterm on both serial console and on virtual console when i log over ssh or rsh. i have same screen size. and ALMOST all programs behave the same way, including full screen programs like mc or vi or even alpine. including colors,sizes etc. the only exception is joe editor. that doesn't work at all. Actually - it display few upper-left characters of it's status bar and nothing else. All i can is to blindly type CTRL-C to exit. switching TERM to vt100 or vt220 doesn't change things at all. any idea why?
