I re-thought the method a bit, and went with something slightly more hackish, plus added code to deal with the case where one uses -h or -Dh in /boot.config (thus setting boot_serial=YES). The Forth code can probably be simplified, but since I got this to work, I'll submit a PR for the whole thing. We can hash out details/improvements there. \ Used when serial console is detected (-|+ characters) 45 constant ascii_dash 124 constant ascii_pipe 43 constant ascii_plus : set_serial_charset ( -- ) s" console" getenv dup -1 = if drop exit then s" comconsole" compare-insensitive 0= if drop ascii_dash h_el ! ascii_pipe v_el ! ascii_plus lt_el ! ascii_plus lb_el ! ascii_plus rt_el ! ascii_plus rb_el ! then s" boot_serial" getenv dup -1 = if drop exit then s" YES" compare-insensitive 0= if drop ascii_dash h_el ! ascii_pipe v_el ! ascii_plus lt_el ! ascii_plus lb_el ! ascii_plus rt_el ! ascii_plus rb_el ! then ; set_serial_charset should be called after f_single in frames.4th. I just tested it on our development box, which uses -S115200 -Dh in /boot.config and nothing serial-related in loader.conf: +-----------------------------------------+ | | | | ______ | | | ____| __ ___ ___ | Welcome to FreeBSD! | | |__ | '__/ _ \/ _ \ | | | __|| | | __/ __/ | | | | | | | | | | 1.
