trouble starting diald

I've been having some trouble getting diald to work.  It connects to
the remote system fine, but when pppd runs it attempts to open
/dev/cua2 (which is where my modem is) and gets EBUSY.

Feb  2 20:38:24 sfere diald[9242]: Delaying 30 seconds before clear to dial.

I've tried doing this with nothing in /etc/ppp/options at all; the
above was tried with exactly the following active:

	asyncmap 0
	lcp-echo-interval 30
	lcp-echo-failure 4

I've tried adding `passive' to that but it made no difference.

I'm at a loss as to where pppd gets `/dev/cua2' from; I refer to it in
all configuration files and scripts as /dev/modem, which is a symlink
to it on my system.  The first reference to it in strace is as
follows:

9090  SYS_136(0, 0x6, 0x18, 0x40001fb0, 0x80016e8) = 0

I'm using kernel 1.3.59, ppp 2.2.0e-2, diald 0.10-2, netbase 1.22-1,
netstd 1.25-1.  Ordinary ppp connections work just fine.

Does anyone have any ideas?
