Please note, that in this menu, when i.e. port name COM4 is given the address 3F8 and IRQ 4,
physically it will refer to Allegro COM1 port connector. At the same time the serial port name
COM1 can be given different address and IRQ level.
The base I/O address of the extension card is given in hexadecimal notation and resides on an
even 32-byte (20H) boundary. This address is assigned usually to the first serial port of the card.
The following ports require 8 bytes of I/O space for each port.
Settings shown in the menu describe COM1 as a standard Allegro (or Pro4000) serial port COM1,
and two ports COM3 and COM4 (associated with extension card) are set based on the assigned I/
O Base Address 380H and IRQ 5 for the serial extension card. This base address is usually displayed
during rebooting Allegro and Pro4000 (see Appendix D).
Please note that any names from COM1 to COM12 can be specified in proper menus, as long as
correct parameters (address and IRQ level) will be assigned to these names in Advanced COM
Setup menu.
Please refer to Appendix D (PCMCIA Card Installation) of this manual or to serial extension card
manufacturer documentation for more information regarding serial port settings.
After all the parameters in the Advanced COM Setup menu are updated press the function key
F1
to accept the displayed settings. The program will return to the Main menu. Updated settings will
be written to the initial file and they will be given as default parameters in the subsequent System
Setup menu display.
To return to original settings (state before this option was selected) press the function key
F2
. All
parameters will be reset to initial settings and the program will return to the Main menu.
