RaspberryPi OS seems to be based on Debian Buster which means its
Linphone is outdated (still version 3.12 IIRC).  So, you'd probably
have to modify the source code by hand yourself and recompile.  That's
probably not the answer you hoped for.  If you decide to go down that
road increasing PROMPT_MAX_LEN in linphone/console/linphonec.h should
probably be all that is necessary.

Otherwise you'll have to wait till such a change might trickle down
from either Debian (I've put it on my TODO list) or elsewhere.  Also,
current linphone has a tool called lp-sendmsg (which is not yet in
Debian, but will be soon, probably as a backport for Bullseye), and
this tool should be able to send messages of sizes only limited by the
maximum command line length.
