Valid 16550 UART settings

Valid 16550 UART settings

Is it valid by the protocol of a FFUART 16550 to configure one side (Machine A) to 155200 baud rate and the other side (Machine B) to 1200? Should I expect the connection to work flawlessly in the lower rate?

"The UART cannot work with different baud rates on two sides.

16550 UART always tramsmits bits with it's own frequency, and is expecting to receive bits (after detecting the start bit) at it's own frequency too. The transmit/receive process is nicely described on Wikipedia, and this is an example of datasheet for 16550 compatible UART from National Semiconductor."
