+Subject: [PATCH] src/sysdep.h: remove cfset{i,o}speed macros for glibc
+
+glibc 2.42 added support for arbitrary termios speeds on Linux, i.e.
+speed_t and Bxxx defines changed from bitmasks to unsigned integers:
+Therefore speed_t can no longer be used together with c_flag's internal
+bitmask CBAUD.
+
+When minicom is compiled on such a system the baudrate setting is broken
+and the user experiences garbled UART output.
+
+Remove the macros for glibc, i.e. call cfset{i,o}speed() instead.
+
+Fixes #17
+
+Upstream-Status: Backport [https://salsa.debian.org/minicom-team/minicom/-/commit/964ae563cb5a78545ae1a4a3b6784c69ec73bc48]
