Hi,

 Here's v2 of the outstanding fixes for Oxford Semiconductor 950 UARTs, 
comprising an chip-specific clock handling implementation for accurate 
baud rate selection including higher baud rates and FIFO rx trigger level 
configuration.

 NB I have since had an opportunity to check what transceiver chips have 
been used with the option card I have been experimenting with, and they've 
turned out to be the Zywyn ZT3243F, specified for up to 1Mbps, so no 
surprise they eventually gave up as the rates I have tried increased, and 
quite interesting it was only at 4Mbps that they did it.

 Please apply.

  Maciej
