[ipxe-devel] serial arrow keys broken

[Jarrod Johnson]

#define GETKEY_TIMEOUT ( TICKS_PER_SEC / 4 )

What happens if you changed that to 2 instead of 4?

Speaking of issues, FWIW, if you are in something that sends a cursor key
application mode (e.g. esxi serial console), then arrow keys might not work
based on what I see in code review.  ESC [ A is recogized as up arrow, but
in that mode a VT100 terminal will send ESC O A instead (etc).
