Re: How to build a driver for 16C552 on EP931X

I wasn't aware they had such a driver.

We are using the Exar ST16C554 (Quad UART) with the standard MS
com16550.dll driver bundled with Platform Builder. It works fine,
although in our case (SH4 processor) we had to make a few minor tweaks
to the PDD code for our system.
More recently I got the isr16550.dll installable ISR (unmodified) going
with this device also, and that makes a significant difference to our
applications also (much less thread switching and data loss at the UART
rx fifo).

Does Exar's driver work with isr16550.dll? Does it offer any other
improvements over the standard MS com16550.dll driver?
