It can handle speeds up to 19.2 kbps quite OK.

Try VT100 v2.9A and see it EVER drops a character.
Try Dnet at 19.2 Kbps and see if it ever fails.  I have used both
of these packages at the above speeds and never had a problem.
I did notice that the Dnet throughput was lower at 38.4 Kbps than at
19.2kps, so there appears to be some sort of interaction at *that*
speed, but nothing lower than that...  Matt didn't have much to say
about the slower rates at 38.4, so I guess he never got around to
fully tuning the software/isolating the bottleneck in the Dnet
code at that speed.

Dnet was under AmigaDOS 1.2 on a B2000, with a 68010.
VT100 under AmigaDOS 1.2 and 1.3, same machine as above.

I seem to remember hearing the Bryce was giving the serial drivers
a work-over for 1.4, or maybe a few too many of my neurons mis-fired
at the wrong time.  Maybe some of the folks at Commodore could
hint if 1.4 will have improved serial driver support...
