[. . . ] (DOS Remote Control is not available over cable or wireless. ) If you do not have access to the host, someone will have to load the TSRs and enable the port for you. Once the TSRs are loaded and ports are enabled, the host can be left running Windows or DOS. Running a DOS session when the TSRs are loaded on the host When you begin a Remote Control session with a host running the LapLink TSRs, you may see the DOS prompt, a DOS program, or a Windows program, depending on the status of the host. You can also start Windows. Using the Services: Remote Control, File Transfer, and Chat 61 Using DOS in Remote Control In the Remote control session shown here, the guest is accessing DOS on the host through a window ("DOS box"). When a guest accesses DOS and DOS programs through a window, there is no need to load the DOS Remote Control TSR programs on the host. In the Remote Control session shown here, the guest is accessing DOS in a full-screen view, either from within Windows or while Windows is not running. To allow a guest to view the DOS prompt or a DOS program in a fullscreen view, the DOS Remote Control TSRs must be loaded on the host. ç From Windows, you can run full-screen DOS programs. You can also exit Windows and operate the programs from DOS. Go to topic summary ! Some DOS programs run full screen in exclusive mode. These programs can substantially reduce the speed of communications between the computers. It's best to avoid operating these programs during a Remote Control session unless you can use them in something other than the exclusive mode. ics mode, use text mode to speed communications. If you are using a DOS program that can run in either text or graph- 62 Chapter 3 Using DOS Remote Control Preparing a host for DOS Remote Control T o prepare a host computer for DOS Remote Control, exit Windows and load the LapLink TSR programs by typing LOADRC in the LapLink directory. Loading the TSRs If you enabled a modem or network port when you installed LapLink, you should be ready for a DOS Remote Control session over that port. To load the TSRs: 1 2 3 If you are running Windows, exit and return to DOS. Type the following and press ENTER: LOADRC You can now run Windows or remain in DOS. A guest can connect in either case. Unloading the TSRs When you no longer need the TSRs, you can unload them and free memory for use by DOS. To unload the TSRs: 1 2 3 If you are running Windows, exit and return to DOS. Type the following and press ENTER: UNLOADRC If you instructed the LapLink Setup program to modify your AUTOEXEC. BAT file, the TSRs are loaded whenever you boot your computer. To modify the file so that the TSRs are no longer loaded automatically, delete the line that loads LOADRC. BAT. Determining which TSRs are loaded on the host When you load the TSRs, you prepare the host for DOS Remote Control by modem or network, by modem only, or by network only. (When a host is prepared for modem or network, a guest can connect to it over either modem or network, but not both at the same time. ) You can determine which type of connection is to be allowed by the TSRs you load. Using the Services: Remote Control, File Transfer, and Chat 63 To determine the type of connection allowed in a DOS session: 1 2 3 Start LapLink on the host. Under DOS Connection Options, select one of these options: Modem Only, Network Only, or Modem and Network. After each option you see the number of kilobytes of memory required by the TSR for that type of connection. You can accept the current setting or select a different one. 4 Choose OK. If you changed the setting, the change will not take effect until you reload the TSRs: Exit Windows, unload the TSRs if they are loaded, and load them again. You can set up a host so that a guest's view of the host screen is updated more often: type a lower value in the Scan Priority box, under DOS Video Options. (A lower value will also slow operations somewhat. ) Conserving DOS memory by loading the TSRs high When you type LOADRC, you are using a batch file (LOADRC. BAT) which loads three TSRs into memory. Using this batch file, however, may not take maximum advantage of the memory available on your computer. Instead of using LOADRC. BAT, you can create your own batch file to load as much as possible of the TSRs into the Upper Memory Blocks (UMBs) of your computer's memory.
