Title:
Device name limited to 39 characters
Status in “digitemp” package in Ubuntu:
Fix Released
Bug description:
Recent udev in Ubuntu includes nifty permanent mappings for serial
devices; for example, my 1wire master shows up as /dev/serial/by-id
/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0. However, when I try to
use this with digitemp:
$ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0

Error, serial port '/dev/serial/by-id/usb-FTDI_FT232R_USB_U' does not exists!
Attached is a patch bumping this limit from 39 (40 minus null) chars
to 1023 (1024), fixing the problem:
$ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0
