I had no problem with the sio in FreeBSD 1.0.EPSILON, both in the "install
floppy" kernel and in kernels that I built.

Now that I've upgraded to the "release" version and built my own kernel, all
stty operations on /dev/tty01 tell me the device is not configured. A 'nm' 
dump on conf.o and sio.o shows the symbols, U and T respectively. The kernel 
links clean, and when it boots it sees the card and detects that it has a 
16550 UART, and reports the fact in the bootup messages.

The /dev/tty01 major number matches the entry number in conf.c (28), the 
minor number is one. The modem is on COM1 (3F8) IRQ4, and the entry in my 
kernel config file matches these. The modem continues to work fine under 
OS/2, which is how I'm logged in to post this message.

Any suggestions on what to look at next?

Thanks.
