  ****************************************************************
  01.A sequence of TSO commands executed via RDz's IRemoteCommand
     API performs much slower than it would if the commands were
     executed directly.
  

Problem conclusion

• 01.There are two reasons why the TSO commands have performance
     problems. First, the reading and writing to and from the
     ISPF client gateway is suboptimal (reading and writing only
     1 byte at a time). Second, an artificial 1 second delay had
     been introduced by RDz in 2011 to circumvent an ISPF client
     gateway concurrency issue. That ISPF issue was resolved as
     of v2r1 so my solution is implemented to only avoid the
     artificial delay if the os is v2r1 or beyond.
