Ad ding COM ports un der Wind ows 9x
To add a COM port to your system configuration, run the “Add New
Hardware” wizard. It is not recommendable to run the automatic hardware
detection!
Add the new COM port explicitly instead. You will get some (presumably
wrong) port address and IRQ. Change these according to the jumper
configuration you set before. After having made these changes to the
Windows 9x configuration, you will have to reboot the system, before they
can get into effect. It is not recommended, however, to reboot before having
entered the port address and IRQ correctly.
In this manual the COM ports are numbered from COM5 to COM8. The
origin of this numbering is from the BEETLE, which has COM1 to COM4 on
the motherboard. It is recommended for consistency, that you use this
numbering also, regardless whether you have e.g. a BEETLE (with COM
ports 1,...,4) or a PC (with e.g. only COM1 and 2).
To provide for a numbering according to that, the following procedure is
recommendable:
n
Run the Add New Hard wa re wi zard to con fi gu re new COM ports, so ad -
ding pos si bly COM3, COM4, if not al rea dy pre sent and COM5, COM6
and (if you have) COM7 and COM8
n
De le te COM ports, that are phy si cal ly not avai la ble (i.e. ser ved as apla -
ce hol der)
n

The automatic hardware detection under Windows 9x may lead to problems,
so you should do without! On BEETLE systems, the automatic hardware
detection may even lead to activation of the internal UPS with the effect,
that it may be impossible to switch off the system later. In such a situation a
call of the RDI utility POWEROFF.EXE e. g. in DOS mode is required.
