From 61fa8d694b8547894b57ea0d99d0120a58f6ebf8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Frank=20Sch=C3=A4fer?= Date: Tue, 6 Aug 2013 19:26:28 +0200 Subject: [PATCH] usb: pl2303: also use the divisor based baud rate encoding method for baud rates < 115200 with HX chips MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that the divisor based baud rate encoding method has been fixed and extended, it can also be used for baud rates < 115200 baud with HX chips. This makes it possible to adjust the baud rate almost continuously instead of just beeing able to select between 16 fixed standard values. Tested with a PL2303HX 04463A (week 46, 2004, rev 3A).
