USING EXPLANDED/EXTENDED MEMORY WITH TELEMAGIC V12 (564)
         --------------------------------------------------------

Q:  How can I get TeleMagic to use Expanded (EMS) or Extended (XMS)  
    memory? 
 
A:  Starting with V12, TeleMagic can use EMS and/or XMS by setting the  
    TELEMAGIC environment variable. At the DOS prompt user must setup
    the environment as follow: 
 		       
          SET TELEMAGIC=/OP1/OO64         && If EMS available 
          SET TELEMAGIC=/OU1/OO64         && If XMS available 
          SET TELEMAGIC=/OU1/OP1/OO64     && If Both available 

         note:  These are all upper case O, not 0 (zeros)
 
   Some memory manager softwares such as QEMM, provide both EMS and XMS. 
   If no EMS or XMS is available and this environment variable is set,  
   then system will hang and must cold boot. 
 
   What do you gain by this: 
   ------------------------- 
   When is setup properly, you will gain about 30K more memory. This is 
   because TeleMagic will no longer uses the main memory for overlay. 
   Also on a large network, TeleMagic should run faster since the       
   MAGIC.OVL will be loaded onto EMS and/or XMS and no longer is required 
   to get the called procedure from the file server until the 64K area is 
   filled. This will reduce the network traffic. 
 
   How do you optimize this: 
   ------------------------- 
   You can increase the the amount of memory for OO option untill you see 
   the avaialable memory reported by F4 is dropped down.  Generally with 
   /OP1 you only should use /OO64, but with /OU1 you can set to the     
   largest upper memory block (ie /OO128). If you don't have enough     
   information on your system or you are not sure follow these steps. 
      a. Run TeleMagic and check the available memory by touching F4. 
      b. Exit TeleMagic and type SET TELEMAGIC=/OU1/OO64. 
      c. Run TeleMagic again and check the available memory now and it  
         should be around 30K more than before. 
      d. Now exit again and increase 64 to 128 and then run TM. If your 
         memory was less than what you had before, then you must set it 
         back to 64, otherwise you are OK. 
 
   Note: You must know if you have EMS or XMS available. Again QEMM     
         provides both EMS and XMS.  DOS 5.0 could provide EMS and      
         XMS depending on your setup. 
 
   Information Screen (F4) 
   ----------------------- 
   Now displays the environment variable if it is set and also displays 
   pool size in K. This number should be equal to whatever is set for 
   OO options. So if you set TELEMAGIC=/OU1/OO64 then it should report 
   64K for Pool Size.

   Compatibility issue: 
   -------------------- 
   We have tested this under DOS 3.3 and DOS 5.0 and beleive that it will 
   work with other DOS versions in between. 

   We also have tested this with the following memory managers. 
      a. QEMM386 
      b. Netroom 
      c. DOS 5.0 HIMEM.SYS and EMM386.EXE   (386 System Only) 
 
   Important Note: 
   --------------- 
   Do not use EMSNET?.EXE when using this feature. Instead use NET?.COM. 
   You may use NET3, NET4 or NETX. Using EMSNETX will cause the system to 
  hang when DOS window (F3) is invoked.
