[Casper]

  Hi,

  I wanted to setup hylafax and find problem, that there is no device 
cuaa...

%uname -a
FreeBSD Test 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Sun May  7 04:32:43 UTC 
2006     root at opus.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

%ls /dev/cua*
/dev/cuad0      /dev/cuad0.init /dev/cuad0.lock


In my older computer:

FreeBSD sadkis.lv 5.4-RELEASE-p7 FreeBSD 5.4-RELEASE-p7 #0: Fri Sep  9 
12:47:55 EEST 2005     root at sadkis.lv:/usr/src/sys/i386/compile/SADKIS  i386

root at sadkis$ ls /dev/cua*
/dev/cuaa0      /dev/cuaia0     /dev/cuala0
/dev/cuaa1      /dev/cuaia1     /dev/cuala1



Is device name changed?

tnx,
K.
