Hi, It's quite possible that I misunderstand your question, but anyway:
Alt-Sysrq-<key> is a route into the kernel sysrq handler instead of a route into the shell that the serial console is connected to, so something needs to signal that condition (like a BREAK).
Or a specialized (serial) console app could know other ways of recognizing sysrq keys. Or you could use /proc/sysrq-trigger: echo b > /proc/sysrq-trigger
