  1.           07/05/92  2.25 While experimenting with some programs of my own I
  2.                          found a some errors in the disabling of the IRQ
  3.                          masks on the Interrupt Controller when exiting from
  4.                          QBserial. The program has been changed so that if
  5.                          the IRQ you specify is already turned ON when
  6.                          OpenComm executes, QBserial will leave it ON when
  7.                          you do a CloseComm. In versions since 2.10, the IRQ
  8.                          mask was always turned OFF when CloseComm was
  9.                          executed. This caused other communications programs
  10.                          such as BBS's that don't reset the port when
  11.                          returning from QBserial to appear to "lock up" when
  12.                          they regained control.
