It seems like his particular setup is the limiting factor. He should have no problems with 56k rs-232 wih proper cabling. The mac had a dedicated serial controller used for rs-232 and rs-422.

LocalTalk wasn't speedy and we were pretty thrilled when we got macs that could support 10/t ethernet, but there was a distinct charm to LocalTalk. (like, the terminators for the cabling consisting of a resistor sticking out of an rj-11 jack!)
I still have a few Dayna Ethernet to LocalTalk bridges I the garage...
- makomk 13y agoAccording to that article, the fastest widely-supported RS232 speed that chip can communicate at is 19.2 kbit/s - the onboard clock generator simply doesn't support any of the standard speeds above that.

Linux CP210x method described in http://bb.osmocom.org/trac/wiki/Hardware/CP210xTutorial http://bb.osmocom.org/trac/wiki/Hardware/CP210xTutorial FTDI application note on non-standard baudrates: http://www.ftdichip.com/Documents/AppNotes/AN232B-05_BaudRates.pdf http://www.ftdichip.com/Documents/AppNotes/AN232B-05_BaudRat...
