Actually, under Solaris the callout devices are /dev/cua/[a-z], linked to
/devices/cpu-unit*/bootbus/zs*:[a-z],cu on a multi-processor machine or to
/devices/sbus* as Ray mentions below, and are specified in /etc/uucp/Devices

A rose by any other name would smell as sweet ;)

Actually, it's not the same. Solaris is the SVR4-compliant version of Sun's
Unix, which started with SunOS-4.1.3 (officially that was Solaris 1.1 I
believe). However, Solaris 2.x.y versions are SunOS 5.x.y - eg Solaris 2.5.1
is SunOS 5.5.1 when uname prints its output.

For those who care (not that that's anybody these days ;>) if you refer to
SunOS, then it's 4.1.3 or before, and Solaris is 2.x since Solaris 1.x was by
most accounts pretty unusable for both the SVR4 and BSD crowds unless you
disabled the SVR4 stuff ;)

It shouldn't be - Sun's stated determination for Solaris/{x86|ppc} is that the
only difference (apart from booting which kinda still depends on lusing PC
bios) is that the cpu architecture is different. Applications and utilities
operate the same (except, as I mentioned, for format and boot), and will
merely need to be recompiled to run on either sparc, intel or powerpc.




cheers,
