I have the datasheet (although 22 pages is a bit large for a "sheet") and I've read it. The way I read it, 115200 Kbps with a 1.8432 MHz crystal calls for a divisor of one, which is acceptable up to crystal frequencies up to 4 MHz (section 8.3, paragraph 1, sentence 2). Care to provide any hints? Like page and paragraph numbers? -- David E.
