- I have a Blizzard1230MKIV (50MHz) in my A1200 and I can use 57600 safely.
- I even run ppp.device at 57600 under AmiTCP.
- Over internet there are lot of unpacked data (html text and so on) so 57600
- isn't a overkill. 115200 gives me too many overruns :(
- The serial hardware is really jurassic but then remember that the PeCes could only
- have 9600 (some claim 19200) with the "same" hardware.
