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.
