Any insight you can provide on the following multiple serial port
problem would be appreciated. Duane Mattern raf5de6k@yahoo.com
I’m using a Sealevel communication card under QNX RTP Neutrino.
The card is a 2 port PCI communication card and it’s operation tests
okay as configured under Windows NT using the Sealevel provided
software utility. Under QNX RTP, only one of the two ports tests out
using a loop-back connection and qtalk.
I’ve been using devc-ser8250 -u1 3f8,4 -u2 2f8,3 -u3 6100,9 -u4 6200,9
to configure the ports after slay’ing devc-ser8250. Ports 1,2, 4 work fine,
which are the normal PC 1st 2 ports and the 2nd port on the Sealevel card.
The first port on the Sealevel card never works.
pci -v yields the following for the Sealevel card:
