Karen,

   I still have an external modem on my desktop which I access through
a USB to serial converter, very, very occasionally.

   To set up the serial modem, I installed and run wvdial...

$ sudo dnf -y install wvdial  
$ sudo wvdialconf /etc/create 

   On my desktop, the modem is at /dev/ttyUSB0.
