Tom> I am a little concerned that the first time you use it, the Tom> driver logs to dmesg: Tom> WARNING: driver rp should register devices with make_dev() (dev_t = Tom> "#rp/0x10082") While I haven't tested it, I expect that this message goes away with FreeBSD 4.7. The rp driver got some work done to it between 4.6 and 4.7. http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/rp/rp.c Tom> Has the driver been updated since FreeBSD 4.5? (Yeah, our Tom> RocketPorts are on older machines... a testament to how reliable Tom> FreeBSD 4.x is :-) ...we haven't needed to upgrade them). Our box handling the serial consoles is also running 4.5. :) Tom> My other concern is that the RocketPorts have RJ45 connectors and Tom> finding the right cable is sometimes difficult.

There is no standard for running a RS232 serial connection over RJ45 connectors like there is for DB-25 and DB-9 connectors. I wish there were, but.... We just make our own cables and ends. Using flat satin cable, putting the RJ45 ends on is trivial, and Comtrol's pin out allows a cross over cable to be built by putting the RJ45 connector on one end of the cable on backwards.
