They still don't do it properly, at least on my 3B2/600G (aka 1000/80)
running SysVr3.2.2. In order to dial out with cu or uucp, I have to
force DCD high which effectively means I can't do full modem control
on bi-directional lines. It seems uugetty is still broken :-(
The SVR3 HDB does work correctly, but the "stock" SVR3.2 documentation does
NOT tell you how to do it (the SVR3.2/386 manuals DO, however). The info can
also be found in the "stock" SVR3.2 "Utilities Release Notes."
I had this problem about a year ago and really created a stink about it here on
the net (remember my: "...even put Mother Theresa on a killing rampage..."? :-)
If you're unable to find the previous info archived, repost your query and I'll
repost all the info again. It seems the HDB bi-directional setup instructions
SHOULD be reposted monthly in light of all the questions about it (due to poor
and inadequate docs) arising here and in other newsgroups.

That document was not in the pile of release notes and manual upgrades for my 3B2 S5R3.2.2 OS. I don't have any hardware manuals, but it appears that DCD is crossed with DSR in the 8 conductor 3B2 AT&T RJ type Modem connectors. To use 'cu', I had to force DCD high on my modem, that is until I rewired the connector: 25 pin 8 conductor RJ to modem towards computer --------- ---------------- 1 ---< Frm Grd >---- 1 2 ---< RD/TD >------ 2 3 ---< TD/RD >------ 3 4 ---< RTS >-------- 8 5 ---< CTS >-------- 5 6 ---< DSR >-------- 7 7 ---< SIG GRD >---- 4 8 ---< DCD 20 ---< DTR >------- 6
