The question, restated, is how to connect the modem one configures
with YAST, to an external serial modem connected via a USB 2.0 to
Serial Port cable adapter. The answer appears to be to link
/dev/ttyUSB0 to one of the devices in the dropdown list in the modem
configuration dialog: I chose /dev/modem. I suppose choosing one of
the USB devices would work as well. Or one of the serial port devices.
The problem arose because the box lacks a serial port and I have an
external serial modem.
