Print to Hardware Port Interrupt 7 and Logite |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Solutions: A customer called who could not use the Print to Hardware Port feature in the 6/29/90 version of WordPerfect 5.1. He had called the manufacturer of his computer and verified the interrupt level at 7 and the base address of 378h which are correct, but the print job would not end, as if he had an incorrect base address. He even tried booting vanilla to eliminate any TSRs with no change in the results. Finally, he found out that he had a board in his computer for a Logitech Handiscanner that was also receiving an interrupt of 7. The manual for the Handiscanner said that it would not interfere with other 7 interrupts if it was not active, but apparently it was conflicting. After he changed the IRQ level on the Handiscanner, Print to Hardware Port in WordPerfect worked fine. |
