From 25241ae22242eb7d178f4a76f2761987a5022d36 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Tue, 16 May 2023 14:53:45 +0100 Subject: util/spkmodem_recv: Add -u flag (no line buffer) printf outputs to stdout, which is line buffered by default. Adding a -u option to disable buffering. Exit when a non-support flag is given, but adhere to current behaviour when no flag is given.
