APAR: PN62140 Problem: AS/400 PC Support product driver conflict. The EHNCPVDD.SYS and EHNPCPDD.SYS drivers have interrupt conflicts with TCP/IP's VDOSTCP.VDD. Failures have also been reported with products other than AS/400 PC Support. Resolution: VDOSTCP.VDD was corrected to forward interrupts instead of discarding them. This APAR has a co-requisite for the AS/400 PC Support product of SA36839.
