mgetty runs successfully and without trouble under Solaris 2.3, 2.4 and
2.5.1 (later versions should also work, but I didn’t get any report so far).
For compilation use -Dsolaris2. With Solaris 2.3 it’s recommended to use
GNU gcc, but with Solaris 2.4 it compiles fine with the SPARCompiler C 3.0.1.
Define CC=cc.
In policy.h you have to define ‘term/a’ or ‘term/b’ as
FAX_MODEM_TTYS. Don’t use the outgoing devices ‘/dev/cua/*’!!
As DEVICE_GROUP you should configure ‘uucp’. If you want allow
to normal users to dial out, add all users allowed to do that, to the group
‘uucp’. Then it’s important to change the permissions of
/var/spool/locks from the default permissions ‘drwxr-xr-x’ to
‘drwxrwsr-x’. Make sure that it’s owned by ‘uucp.uucp’.
Otherwise no one wanting to dial out is able to create a lock file. The
FILE_MODE in policy.h must be ‘0660’ as well.
If you don’t want allow anyone to dial out you should set FILE_MODE
to ‘0640’ or ‘0600’.
For the "notify mail" message to look best, define MAILER in
policy.h to /usr/lib/sendmail and define
NEED_MAIL_HEADERS. So a proper subject header is created.
Nevertheless, /usr/bin/mailx works, as it is the default for SVR4.
If everything compiled well and you did make install, you have to
add an entry to /etc/inittab like the following:
ya:234:respawn:/usr/local/sbin/mgetty -s 38400 -x 3 term/a
Don’t use the Solaris admintool to create any port monitoring
entries in /etc/saf/_sactab and /etc/saf/zsmon/_pmtab.
Many thanks to Stefan Muehlenweg (muehlenw@samhh.hanse.DE) for this section.
Solaris (as all Sun operating systems) seems to be somewhat weird
concerning its handling of the RTS line. I have received two reports that
’sometimes’ a modem hangs during initialization, and won’t talk to mgetty
anymore. In these cases, the problem went away when the modem (an USR
Sportster) was set to AT&R1, which means ’ignore RTS line’. Thanks
to Valerio Di Giampietro for detailing this.
