This is not an OS/2 problem, just a C problem.  I recommend C_ECHO.

You should not use non-ASCII characters in strings, but code the values. 
In cases where this is ambiguous ("\x011\x012\x014NET"), you need
to use the compiler concatenation facility to remove the ambiguity.

C considers strings to be null-terminated, so copying char arrays which are
not null-terminated must use memcpy() rather than strcpy().

Your logic is also messed up, since you will do a write after getting EOF. 
On success, fread() returns the number of bytes read, which you should
check when reading from a fixed-block binary format file:

   while(sizeof(struct username_in) ==
         fread(&user, sizeof(struct username_in), 1, in)) {

      memset(mtag2, 0, sizeof(struct copy_name));    /* zero mtag2 */

      memcpy(mtag2.delim, "\x82\x01", sizeof(mtag2.delim));

      memcpy(mtag2.name, user.name, sizeof(mtag2.name));

      memcpy(mtag2.areas,
             "\x01" "1" "\x01" "2"
"\x01" "4NET",
             sizeof(mtag2.areas));

      fwrite(&mtag2, sizeof(struct copy_name), 1, out);
   }
