WordPerfect® 6.0 for DOS

Problem

Symptoms: FAXDIR generates an Error 11 when trying to load. User says modem is on a valid COM port (i.e., 1,2,3,4.) Solutions: Verify the selected IRQ. This will require the user knowing which non-standard IRQ has been selected or will require checking the IRQ setup in another data/fax communications program that works. The standard IRQ's are:

Port Base I/O IRQ

Com 1 03f8 4
Com 2 02f8 3
Com 3 02f8 4
Com 4 02e8 3

Example:

The user is on com 3 IRQ 5. When he/she runs Setup for the CAS Manager, the user is unable to select com 3 IRQ 5. Com 3 defaults to IRQ 4.

To select a non-standard IRQ, in Setup for the CAS Manager set the port to User by pressing the space bar to toggle between com ports. After the correct port is selected, press Enter and set the base address (see the settings under Base I/O above). After the base address is set, press Enter and set the IRQ number. With Faxdir, only IRQ's 2-7 are available. Press F10 to save the settings.

Faxdir will read the port the modem is jumpered for, even though the customer will set the com port to User.

Note: It is recommended that IRQ 2 not be used as this is often a cascade IRQ used by DOS. Causes: Although the com port is set to a valid number, the IRQ may not coincide with the selected com port.
