Hi there!
I am also trying to setup dialing into a Mac OS X server machine.
Here is what I've figured out:
In the /dev directory there are 2 devices related to the internal modem: tty.modem and cu.modem.
tty.modem is for incoming calls
cu.modem is for outgoing calls
To verify the above in a terminal window type:
ioreg -c IOSerialBSDClient
You will get several lines of output. Locate the line IOSerialBSDClient, under that block you will
see the lines: "IODialinDevice", "IOCalloutDevice".
The Internet Connect application uses cu.modem to dial out.
In the /etc/ttys file I added the line:
tty.modem "/usr/libexec/getty std.9600" dialup on
In order to get a getty running on that port I typed in a terminal
window: kill -HUP 1
After giving the above command my machine got in a hang state for several seconds. I solved this hanging problem by installing
a new version of AppleSCCSerial kernel extension.
Now my modem connects, but I don't get a login prompt.
I believe the problem is because getty opens the modem port as soon as it runs. The getty process should be in an idle state and
open the port after the two modems have established a connection.
Thanks for any info.
