Aside from the avoidance of CPU overhead, what does the ET/5025 buy me? (I don't understand "a lot more bandwidth" - I can definitely do 115200 with a 16550, and since terminal adapters generally cannot do 128000 speeds in async mode, the ET/5025 would be limited to the same speed... certainly no more bandwidth at all....). Now if you can find yourself a TA that can do 230.4 or 460.8, and the ET/5025 is able to do that in async, that might be a benefit. I've retrofitted 16550 ports to run at such speeds and the CPU does eventually reach a point where it has difficulty keeping up on a consistent basis (although this is more likely a driver issue...?) ...
