3-3-95                      Windows & Addresses & IRQs

     Windows 3.1 has  the addresses for COM3/4 set wrong. Use the  control
panel  and  goto Comport, then  Settings, then Advanced  screen.  Set  com4
address  02E8, IRQ 3, com3 03E8 IRQ 4. If you set another IRQ on the  modem
then  use the control panel to set them for Windows. (Windows  3.0  doesn't
have  any settings for COMport3/4, so you have to do a special  setup,  ask
MS.)  Make sure no other Windows drivers are loaded for comports.  Even  if
you  are  not USING com3/4, make sure they are set correctly!  MSD  reports
COMports wrong, when a port is skipped. Don't set over 19,200bps. If 
Windows isn't saving the Address/Irq correctly, you can edit the SYSTEM.INI 
file and put them in yourself. They go just above the [standard] line in 
the INI file.

example:
......
COM3Irq=5
COM3Base=03E8
COM4Irq=3
COM4Base=02E8
COM2Irq=3
COM2Base=02F8
                 (be sure to leave this line blank)
[standard]

     If  you're  using  the external port and  having  comport  errors, try
setting Com/3/4 correctly, as that sometimes still causes a problem.  Don't
beleive MSD as it's not accurate.

     Windows  com.drv can only handle up to 19,200bps and be  reliable,  so
don't set any Windows com/fax programs higher, unless you get a replacement
driver like Turbocom.drv.

>>>   You cannot have a Dos  TSR (like Faxman, Faxcap, Faxcom) loaded  when
you  want  to use a Windows com or fax program. And if you have  a  Windows
com/fax  driver open/loaded, it controls the port, and can mess up  both  a
Windows or DOS fax or data program. (give errors when you try to access the
port).  Windows  drivers  might cause a problem too,  like  a  screensaver.
Running a DOS program from Windows may fail too. And strange as it may 
sound, having wrong settings in Windows can mess up some Dos software using 
the modem.

     If  all  else  fails, then you may need to call  Microsoft.  For  some
reason,  sometimes when you change the addres/irq it does not Save the  new
settings. MS has a debug procedure to 'fix' your comport setup.
