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 !

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:
