+Subject: [PATCH] Don't use high baudrates when not available
+
+On certain architectures (namely Sparc), the maximum baud rate exposed
+by the kernel headers is B2000000. Therefore, the current libserial
+code doesn't build for the Sparc and Sparc64 architectures due to
+this.
+
+In order to address this problem, this patch tests the value of
+__MAX_BAUD. If it's higher than B2000000 then we assume we're on an
+architecture that supports all baud rates up to B4000000. Otherwise,
+we simply don't support the baud rates above B2000000.
+
+Fixes build failures such as:
+
+./SerialPort.h:88:24: error: 'B2500000' was not declared in this scope
+         BAUD_2500000 = B2500000,
