OSPRPOLL - HOW TO DISABLE POLLING IN OS/2 WARP FOR PRINTING
10/21/94
================================================================
HOW TO DISABLE POLLING IN OS/2 WARP FOR PRINTING
================================================================
Please Read Entire Document for Full Explanation of Procedures
----------------------------------------------------------------
OS/2 WARP Defaults to Polling for printing, rather than using IRQ
settings as in OS/2 2.1, 2.11 and OS/2 for Windows.
SYMPTOMS:
1. Printing slower than in OS/2 2.1, 2.11 or OS/2 for Windows.
2. Printing interrupted by other processes, when multi-tasking.
3. Printing uses excessive CPU resources, shown in the pulse
utility.
NOTE: This may occur in non-microchannel machines.
RESOLUTION:
To change printing to IRQ 7 for LPT1 and IRQ 5 for LPT2 a
flag, / (forward slash) is added to the CONFIG.SYS to
disable the Polling method.
PROCEDURE:
With a text editor, modify the CONFIG.SYS, type:
BASEDEV=PRINT01.SYS /IRQ
This disables polling and enables IRQ7 for LPT1 and
IRQ5 for LPT2.
