PC>   rc = DosSuspendThread(pdata->tidReadThread);

DosSuspendThread is not a good idea.  Use a semaphore instead; this way
your read thread will block in a controlled place.

 PC> VOID    WaitForSession(PTID ptid, ULONG SessID)

You're right to ask for advice...use a termination queue instead.  Here is
a (16bit) sample (I wrote this program before the START command became
flexible):


 #define INCL_NOPM
 #define INCL_DOS
 #define INCL_DOSERRORS
 #include 
 #include 
 #include 
 #include 
 #include 

 void showuse(void)
 {
    
printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\n");
     printf("X DSS       (DosStartSession)       P.Fitzsimmons
91/09/02 X\n");
     printf("X                                             Version
0.00 X\n");
     printf("X Usage:   DSS [options]  [program
arguments] X\n");
     printf("X Purpose:  Start a new session.                         
 X\n");
     printf("X Options:  /F    - Switch program to foreground.        
 X\n");
     printf("X           /WIN  - Run in a VIO window session.         
 X\n");
     printf("X           /FS   - Run in a full screen session.        
 X\n");
     printf("X           /PM   - Run as a PM program.                 
 X\n");
     printf("X           /WAIT - Wait for program to complete (default
 X\n");
     printf("X                   is asynchronus)                      
 X\n");
    
printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\n");
 }
