I can't go faster than 9600 bps! This is because I have some cheap-o 16450 UARTs on my motherboard. What type of UARTs do you and the Linux box have? What you need is 16550. (Under NetBSD, it tells you when you're booting what chips you have. I dunno about FreeBSD. Anyhow, the new version of Net fixes many of these problems, but 19,200 is still a no-go. One solution is to get an "AST" card that has 4 16550-buffered UART com ports on it. I think they're about $50... I will do this in January when I will need those com ports again. FreeBSD 1.1.1.5 (and probably versions back to 1.0.2 from last September) will go as fast as you like with 16450's. I regularly use PPP at 38400 (limited by the speed of the Sparc at the other end). But 57600 and 115K also work OK. - Gene Stark
