7 years ago I tried this today with a very long device name and ran into it.
: [username@workstation ~]$ ; grep PTT direwolf.conf
#PTT /dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0 RTS DTR
PTT /dev/serial/by-path/pci-0000:00:14.0-usb-0:4:1.0-port0 RTS DTR
: [username@workstation ~]$ ; direwolf
Dire Wolf version 1.2
Audio device for both receive and transmit: sysdefault:CARD=PCH (channel 0)
Channel 0: 1200 baud, AFSK 1200 & 2200 Hz, E+, 44100 sample rate.
ERROR can't open device /dev/serial/by-path/ for channel 0 PTT control.
No such file or directory
Note: PTT not configured for channel 0. (Ignore this if using VOX.)
Ready to accept AGW client application 0 on port 8000 ...
Use -p command line option to enable KISS pseudo terminal.
Ready to accept KISS client application on port 8001 ...Yes, I tried both device paths showed by the grep but both end up with the funny unicode character in the output and no working PTT.

Description: Soundcard TNC for APRS
Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder. It can
be used stand-alone to receive APRS messages, as a digipeater, APRStt gateway,
or Internet Gateway (IGate). It can also be used as a virtual TNC for other
applications such as APRSIS32, UI-View32, Xastir, APRS-TW, YAAC, UISS, Linux
AX25, SARTrack, and many others.

I'm using a US Interface Navigator here and I'm trying to use the serial by-id naming convention. The Navigator's six serial ports identify themselves with long names:
root@rpi3:/etc/ax25# ls -la /dev/serial/by-id/ total 0 drwxr-xr-x 2 root root 160 Jul 4 10:42 . drwxr-xr-x 4 root root 80 Jul 4 10:42 .. lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorCAT___2nd_PTT00000000-if00-port0 -> ../../ttyUSB0 lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorCAT___2nd_PTT00000000-if01-port0 -> ../../ttyUSB1 lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorRS232_Config00000002-if00-port0 -> ../../ttyUSB4 lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorRS232_Config__00000002-if01-port0 -> ../../ttyUSB5 lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorWKey_FSK__00000001-if00-port0 -> ../../ttyUSB2 lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorWKey_FSK00000001-if01-port0 -> ../../ttyUSB3
The port I'm trying to use is:
lrwxrwxrwx 1 root root 13 Jul 4 10:42 usb-FTDI_NavigatorCAT___2nd_PTT00000000-if01-port0 -> ../../ttyUSB1
and thus in the direwolf.conf file for Direwolf v1.4, I'm using:
PTT /dev/serial/by-id/usb-FTDI_NavigatorCAT___2nd_PTT00000000-if01-port0 RTS -DTR
Unfortunately, that doesn't work but the short direct interface name DOES work:
PTT /dev/ttyUSB1 RTS -DTR
Can Direwolf be enhanced to deal with longer device names?
