I have kldloaded uchcom. root@testhost-1# uname -a FreeBSD testhost-1.kg4.no 8.0-STABLE FreeBSD 8.0-STABLE #0: Sat Dec 12 23:49:41 CET 2009 root@testhost-1.kg4.no:/usr/obj/usr/src/sys/GENERIC amd64 In /var/log/messages: Dec 27 23:07:43 testhost-1 kernel: ugen1.2: <vendor 0x4348> at usbus1 Dec 27 23:07:43 testhost-1 kernel: ucom0: <vendor 0x4348 USB-SER!, rev 1.10/2.50, addr 2> on usbus1 Dec 27 23:07:43 testhost-1 kernel: ucom0: CH340 detected I took TEMPer.c[1] from Tollef Fog Heen's site, changed the device from /dev/ttyUSB0 to /dev/ttyU0 and compiled with gcc -lm -o TEMPer2 TEMPer2.c and tested it: root@testhost-1# ./TEMPer2 Init starting Init done ^Croot@testhost-1# It hangs after "Init done" until I break out of it with Ctrl-C. This is strange, the same code works fine un Linux: tingo@kg-home:~$ uname -a Linux kg-home 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:01:29 UTC 2009 i686 GNU/Linux tingo@kg-home:~$ ~/work/temper/TEMPer Init starting Init done Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100100000000. 25.000000 Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100000000000. 24.000000 Getting temperature done 0001100000000000. 24.000000 Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100010000000. 24.500000 Getting temperature done 0001100100000000. 25.000000 ^C I wonder if it is the driver in FreeBSD or something different in the tty initialization? Anyway, I have made a FreeBSD[2] and a Linux[3] page with all the details.
