Maybe someone can help me. I installed QNX RTP onto my computer
yesterday but have yet to try the Voyager browser. I have read the Help
files but I may have overlooked something obvious.
The problem is that “devc-ser8250” currently only starts up ports 1 and
2 but my internal modem is on port 3. So I launch “devc-ser8250 -u3
3e8,3”. “ser3” then appears under /dev as it should. I then send an
AT command to the modem but cannot communicate with it. The port
address of ‘3e8’ is one that I determined under my main OS (Windows
98). Unfortunately, I can’t seem to determine the interrupt being used
for this device under Windows so I simply tried IRQ 3, then 4, 5, 6 …
The modem is an AOPEN 56k. Is it simply because “devc-ser8250” is not
the proper driver? I noticed that in the QNX site under “Hardware
Supported” there are no entries for modems, except for PCMCIA modems.
Are only external devices supported?
