The Device tab


Here you can select and configure your modem.

Modem Device

Choose the device appropriate for your hardware.

/dev/ttys0

DOS or Windows® users will know this as COM1, while COM2 is /dev/ttys1 and so on. These devices are the ones normally used on Linux® systems.

/dev/cua0

The first serial line (COM1). COM2 is usually /dev/cua1 and so on. These devices are commonly used on BSD systems, namely FreeBSD, NetBSD and OpenBSD. Older Linux® systems may also have these, although on Linux® they were renamed some time ago to /dev/ttySx.

/dev/ttyI0

On Linux® these belong to internal ISDN cards. These devices emulate a common Hayes compatible modem. /dev/ttyI0 is for the first, /dev/ttyI1 is for the second ISDN card and so on. These devices are only available in the Linux® version.

/dev/modem

Many Linux® distributions make a symbolic link from the real modem device to /dev/modem. You should avoid using this one.. Use the real device that it is pointing to instead.

Flow Control

Select from Hardware (CRTSCTS), Software (XON/XOFF) and no flow control. The recommended setting is Hardware flow control.

Line Termination

Choose the correct “Enter” character sequence for your modem. Most modems will use “CR/LF”, however some modems need a different setting. If you experience trouble while running a login script, play with this parameter.

Connection Speed

Choose from the list of connection speeds supported by your serial port. Note that the serial port supports much higher speeds than your modem in most cases. You should probably start with the highest number available, and only reduce it if you have connection problems.

Use Lock File

Activate this option if you want KPPP to create a lockfile. Under Linux® the folder for such a file will be /var/lock. Programs such as mgetty depend on the existence of such lock files, and KPPP will not work with mgetty if the lock file is not set. Make sure that you don't use the option lock for pppd if you want KPPP to lock the modem, since the pppd option lock will induce pppd to try to lock the modem device. Since KPPP will have already locked the device, pppd will fail, and KPPP will display the error pppd died unexpectedly.

Modem Timeout

This is the time in seconds that KPPP will wait for the CONNECT response from your modem. A setting of about 30 seconds should be sufficient for most purposes.
