To switch your DOS applications between "Full Screen" and "Windowed" mode, depress ALT+ENTER. Each time you depress ALT+ENTER the DOS application will switch modes.
Get in the Command Line
The Windows NT Resource Kit contains a remote command-line utility (REMOTE.EXE) that provides a complete remote command prompt for running batch files and other character-mode tasks across a network. Select the computer you want remote jobs to run on, open a command prompt, and type REMOTE /S cmd.exe unique-id, where unique-id is a character string that uniquely identifies a particular remote session, such as MyRemote1. You can now gain access to the remote session from any other Windows NT machine on your network by typing REMOTE /C computer-name unique-id, where computer-name is the name of the computer on which the REMOTE /S session was run. By default, REMOTE /S provides no security--anyone with access to a Windows NT system and knowlege of the unique-id for a particular session may access it. To restrict access, add /U domain\user to limit the session to use by a particular user from a particular domain.
sPIF Up DOS And OS/2 Apps
Set up a Program Information File (PIF) for DOS and OS/2 applications that need special environmental parameters. PIFs can include custom AUTOEXEC.NT and CONFIG.NT files, which provide an application with such things as extra memory, the start-up directory, multitasking options, shortcut keys and timer emulation. To create a PIF, start PIF Editor from Program Manager's Main group, specify PIF options and select Save As from the File menu.
