Efax can not send a fax.
Socket running on port 9900 efax-0.9a: 17:33:54 Error: can't open serial port /dev/ttyS1: Permission denied efax-0.9a: 17:33:54 failed page /home/andy/Documents/UHC_Appeal.pdf.001 efax-0.9a: 17:33:54 finished - unrecoverable error
I tried most of the suggestions from here.
I had to run it as a superuser.
But the fax fails.
