The default bit rate is 9600 bps. It would be nice to go higher, but there appear to be race conditions which make it unreliable. At least initially, you should run at 9600 bps; after that, there are ways of changing the rate that are themselves changing. Check the kernel configuration files and sysctl. To set the bit rate on the port depends on what software you're using. I still use cu, though it's now gone from the base system, along with its parent uucp. With cu you'd do: cu -s 9600 -l /dev/cuaa0 You can do something similar with tip, which is still around. If you have a firewire connection, that's *much* better. Before you say "no, I don't have that", consider that firewire hardware is very cheap. There's some stuff about it in http://www.lemis.com/papers/AUUG2004/tutorial.pdf, but it would be nice if somebody were to extract this information and put it in the handbook. If anybody wants to, please contact me and I'll supply the source. Greg -- See complete headers for address and phone numbers.
