 BS20001  NAK FROM 3270 CAUSES RETRANSMISSION OF GARBAGE BLOCK. 
  
          WHEN THE 3270 TIP RECEIVES A NAK IT REPROCESS THE TRANS-
          MISSION BLOCK BEFORE RETRANSMISSION, THUS CREATING A GARBAGE
          BLOCK.  THIS IS CAUSED BY THE BUFFER FLAG -BF3TEXTPR-, WHICH
          INDICATES THAT A BLOCK HAS BEEN TEXT PROCESSED, NOT BEING SET.
          THE FLAG IS SET BY OUTPUT TEXT PROCESSING STATE PROGRAM BUT IS
          INADVERTANTLY CLEARED IN PROCEDURE -PT3TEXTPROCESS-.

 BS20002  3270 TIP DOES NOT HANDLE SCREEN SIZES GREATER THAN
          1920 CHARACTERS.
  
          UPDATE THE 3270 TIP TO CHECK THE SCREEN SIZE (PAGE WIDTH
          X PAGE LENGTH) FOR GREATER THAN 1920 CHARACTERS AND SEND
          AN ERASE WRITE ALTERNATE WRITE CODE IN PLACE OF AN ERASE
          WRITE WRITE CODE TO CONDITION THE TERMINAL TO THE CORRECT 
          MODE.  IF A CLEAR IS RECEIVED FROM THE TERMINAL, FORCE AN 
          ERASE/WRITE OR ERASE/WRITE ALTERNATE.

 BS5A001  3270 TIP DOWNS DEVICE IF STATUS WITH THE *IR* BIT SET IS
          RECEIVED. 
  
          SOLUTION - MODIFY THE TIP TO PROCESS THE *IR* BIT CORRECTLY 
                     INSTEAD OF DOWNING THE DEVICE. 
  
          THIS CODE WAS SUPPLIED BY CHRIS TAYLOR OF CAL STATE WITH
          A PSR (SRN=FCT001) HE SUBMITTED AGAINST THE PS VERSION OF 
          THE 3270 TIP (PR=BS2).

 BS5A005  CONNECTIONS ARE NOT TERMINATED WHEN TERMINAL IS POWERED OFF.
  
          THE TIP DOES NOT HANDLE "DEVICE END" SITUATION PROPERLY.
          CURRENTLY WHEN THE TIP RECEIVES A "DEVICE END" CONDITION FROM 
          THE CLUSTER CONTROLLER, IT PUTS THE DEVICE ON A TIMER TO CHECK
          LATER.
  
          THE SOLUTION IS TO MODIFY THE TIP TO HANDLE THE "DEVICE END"
          CONDITION IN THE FOLLOWING MANNER:  
          - IF THE DEVICE IS A CONSOLE, THE DEVICE IS DISCONNECTED. 
          - IF THE DEVICE IS A PRINTER, THEN THE DEVICE IS PUT ON A TIMER 
          TO BE CHECKED LATER FOR BUSY STATUS.

 BS5A007  A 3270 TERMINAL CAN HANG IF EITHER PW OR PG ARE SET TO 0. 
  
          SINCE THE 3270 TIP USES PG TIMES PL AS THE TRANSMISSION BLOCK 
          SIZE, IF EITHER ONE OF THEM IS SET TO 0, THE CONNECTION WILL
          HANG. 
  
          THE SOLUTION IS TO ADD TWO ENTRIES IN THE 3270 TIP ACTION 
          TABLE FOR PAGE WIDTH AND PAGE LENGTH.  THESE VALUES ARE THEN
          RESTRICTED TO 8 @ PAGE LENGTH @ 255, AND 20 @ PAGE WIDTH @
          255.

 BS50010  3270 TIP DOES NOT RELEASE BUFFERS QUEUED TO POWERED OFF 
          TERMINALS.
  
          THIS PROBLEM WAS INTRODUCED BY BS5A001. 
          BS5A001  MODIFIED TO 3270 TIP NOT TO DOWN THE DEVICE IF THE IR
          BIT WAS SET IN THE STATUS WORD.  THIS CAUSED THE PROBLEM WHERE
          THE  3270 TIP WOULD NOT RELEASE BUFFERS FOR DEVICES THAT  WERE
          POWERED OFF SINCE THESE DEVICES SHOWED IR IN THE STATUS WORD. 
  
          THE SOLUTION IS TO REMOVE THE CODE INTRODUCED BY BS5A001.  THE
          REASON THAT WE SIMPLY DO NOT PURGE BS5A001 IS DUE TO THE  FACT
          THAT  SOME OTHER CODE WAS INTRODUCED THAT DELETED SOME OF  THE
          LINES INTRODUCED BY BS5A001.
