-
- Also note that for ttysoftcar to work consistently, you MUST NOT have
- the keyword "local" in the /etc/ttytab entry for the modem port.
-
- For example:
-
- ttya "/usr/etc/getty std.9600" dialup on local secure
- ^^^^^
- REMOVE THIS!!
-
- When you run 'ttysoftcar -a', ttysoftcar scans the /etc/ttytab file
- looking for modem ports. Any entry that has "local" in it will be
- counted as a terminal port and NOT a modem port. Ttysoftcar will
- reset the port for "software" carrier (ignore DCD and always assume
- carrier is on).
-
- If the entry does not have "local", ttysoftcar will know it's a modem
- port and select hardware carrier. This is what you want for a modem
- port - you want it to listen to the "hardware" carrier (the DCD signal
- from the modem).
-
- You can use "ttysoftcar -n ttya" to set the port correctly without
- scanning /etc/ttytab, but your setting will be changed back as soon
- as you reboot your system. The system runs 'ttysoftcar -a' in the
- /etc/rc startup script. If your /etc/ttytab entry isn't correct
- (still has "local" in it), the settings will be put back to the
- incorrect "software carrier" ones.
