To the end that it is an ongoing struggle to get Microsoft to listen
to the needs of the programmer, the following patches are provided
to enable you to patch your copies of BRUN45.EXE and BCOM45.LIB.

Before beginning, make sure you have backup copies of BRUN45.EXE
and BCOM45.LIB.

BCOM45.LIB DTR Patch
--------------------

With Debug in a DOS path, type :

  debug bcom45.lib

Type :

  s cs:0 ffff b0 00 e3 01

Debug should show :

  xxxx:1529

  where xxxx can be any number depending upon where Debug loaded the
  program into memory.  In any case, the number is not important.

Type :

  u 1529

Debug should show :

  MOV   AL,00
  JCXZ  152E
  INC   AX
  ADD   DX,+04
  OUT   DX,AL

This is where QB graciously resets the comm port to parameters it thinks
the comm port should have.

To fix the problem, Type :

  a 1529

  mov   al,01
  [Enter]

  a 152d

  nop
  [Enter]

  where [Enter] is the Enter key (do not type the characters)!


To verify that you typed everything correctly, Type

  u 1529

Debug should show :

  MOV   AL,01
  JCXZ  152E
  NOP
  ADD   DX,+04
  OUT   DX,AL


To save the corrections Type :

  w

Debug should show :

  Writing 35EF7 bytes


Now type Q and you are finished patching BCOM45.LIB



BRUN45.EXE DTR Patch
--------------------

First, rename BRUN45.EXE to BRUN45.X

With Debug in a DOS path, type :

  debug BRUN45.X

Type :

  s cs:0 ffff b0 00 e3 01

Debug should show :

  xxxx:9E78

  where xxxx can be any number depending upon where Debug loaded the
  program into memory.  In any case, the number is not important.

Type :

  u 9e78

Debug should show :

  MOV   AL,00
  JCXZ  9E7D
  INC   AX
  ADD   DX,+04
  OUT   DX,AL

This is where QB graciously resets the comm port to parameters it thinks
the comm port should have.

To fix the problem, Type :

  a 9e78

  mov   al,01
  [Enter]

  a 9e7c

  nop
  [Enter]

  where [Enter] is the Enter key (do not type the characters)!


To verify that you typed everything correctly, Type

  u 9e78

Debug should show :

  MOV   AL,01
  JCXZ  9E7D
  NOP
  ADD   DX,+04
  OUT   DX,AL


To save the corrections Type :

  w

Debug should show :

  Writing 12E80 bytes


Now type Q and you are finished patching BRUN45.X

Rename BRUN45.X back to BRUN45.EXE
