latsetup - Local Area Transport (LAT) setup utility
Specifies that latsetup is run in noncurses and nonmenu-driven mode. Use this option if the terminal you are using does not support curses.
The latsetup command provides an interactive, menu-driven facility for administrating LAT on your system. (For introductory information on LAT, see the lat_intro(7) reference page.)
To use latsetup, LAT must be built into the running kernel, your system must be at run level 3 or 4, and you must be logged in as superuser. For more information, see the Network Administration manual.
Running multiple latsetup processes concurrently on the same machine can cause erroneous information to be presented to the latsetup user and can corrupt the /etc/inittab file.
You can use the latsetup utility to perform the following tasks: Do initial LAT setup Create LAT device special files Add or delete getty entries to or from the /etc/inittab file Execute init q Start or stop the LAT driver Enable or disable LAT automatic startup and shutdown
If LAT is not configured into the running kernel, latsetup only allows you to remove the LAT entries from the /etc/inittab file.
If you enable LAT automatic startup and shutdown, the /sbin/init.d/lat script starts LAT upon reaching run level 3 and stops LAT upon leaving run level 3.
To run latsetup, log in as superuser and enter the following command: # /usr/sbin/latsetup
In the device creation phase, you choose to create SVR4-style or BSD-style devices. (For an explanation of the types of devices, see the Network Administration manual.) A maximum of 620 BSD-style devices is supported. Digital recommends the use of SVR4-style devices. If you need a large number of devices, Digital recommends you use SVR4-style devices.
If you create SVR4 devices using latsetup, and an SVR4 device was mapped as an application port and the device was removed, the port (or service) information remains associated with the minor number corresponding to the device that was removed. Therefore, when latsetup creates more devices, it may create the device that was mapped as an application port (if the device name is within the range of SVR4 devices being created). The latsetup utility does not add a getty entry for the device in the /etc/inittab file. This device is not counted as a newly created SVR4 device, because it is already being used as an application port.
If you delete SVR4 devices using latsetup, and an SVR4 device was mapped as an application port and has an associated getty entry in the inittab file, if the device name is within the range of SVR4 devices being removed, latsetup removes the associated getty entry in the /etc/inittab file. When removing SVR4 devices, latsetup does not remove the device, because it is mapped as an application port. This device is not counted as an SVR4 device that has been removed. The latsetup utility creates device names that directly correspond to minor numbers (for example, SVR4 device /dev/lat/620 corresponds to minor number 620).
If you delete entries in the /etc/inittab file and then run latsetup to make other changes or deletions, latsetup might not be able to complete successfully.
For more information refer to the guide to Network Administration and latcp(8).
Specifies the BSD LAT terminal devices. (Where W is a number from 0 to 9 and X is an alphanumeric character from 0 to 9, a lowercase a to z, or an uppercase A to Z.) LAT supports up to 620 BSD LAT terminal devices. Specifies the SVR4 LAT device special files. (Where n is a number starting at 620 and having no upper limit.) Specifies the LAT control device. Specifies the LAT startup and shutdown script. Specifies LAT customization commands. Sets up the system database to automatically push the ldterm STREAMS module on top of the LAT STREAMS driver each time a LAT tty is opened. Controls the initialization process. Specifies the system configuration file.
Commands: llogin(1), init(8), latcp(8), MAKEDEV(8), strsetup(8).
