If you set up Hardware flowcontrol on the serial lines onboard (/dev/ttya
& /dev/ttyb) youwill have no luck. I do not know if this also applies to
other serial lines.

Fact for the ZILOG chip on the CPU borad is:
If CTS is set to AUTOENABLES (Hardware flowcontrol) the chip will not
allow you to talk to your modem if no carrier is present. This means that
you are no longer able to dial out ....... SORRY :-(
