How do you access the SysRq functions, such as kernel backtrace, when running the
serial port with a terminal emulator? (minicom)
TIA

Well, RTFM.
Documentation/sysrq.txt:
On the serial console (PC style standard serial ports only) -
You send a BREAK, then within 5 seconds a command key. Sending
BREAK twice is interpreted as a normal BREAK.
How to send BREAK from minicom?
# man minicom
/BREAK
you'll find: Ctrl-A F
Enjoy.
