  Hi,

  I am using sane-devel-20000206, Linux 2.2.14, glibc2.0.7.

  The Mustek backend works with a Mustek 600 II N without the net backend. If
  I do the test over the network (using localhost) it doesn't. Standard error
  is:

  [...]
  scanimage: stepped read, 31 bytes... PASS
  scanimage: stepped read, 15 bytes... PASS
  scanimage: stepped read, 7 bytes... PASS
  scanimage: stepped read, 3 bytes... PASS
  scanimage: stopping scanner...
  scanimage: stopping scanner...
  scanimage: stopping scanner...

  The last line is repeated until I stop scanimage by SIGKILL (Ctrl-C and
  SIGTERM doesn't work).

  The debug output is (net & dll set to 255):

  [...]
  scanimage: stepped read, 7 bytes... [dll] read(handle=0x804eac8,data=0x8052348,maxlen=7,lenp=0xbffff320)
  PASS
  scanimage: stepped read, 3 bytes... [dll] read(handle=0x804eac8,data=0x8052348,maxlen=3,lenp=0xbffff320)
  PASS
  [dll] cancel(handle=0x804eac8)
  [dll] close(handle=0x804eac8)
  [dll] exiting
  [dll] calling backend net's exit function
  [net] exiting
  [net] closing dev 0x804ef10, ctl=4
  scanimage: stopping scanner...
  [dll] cancel(handle=0x804eac8)
  scanimage: stopping scanner...
  [dll] cancel(handle=0x804eac8)
  scanimage: stopping scanner...
  [...]

  XSane does however work using network scanning and the Mustek backend. But
  if I cancel during a network scan I get "Speicherzugriffsfehler" (segmentation fault).

  The last lines of the debugging output are:

  [dll] cancel(handle=0x80cd378)
  [dll] read(handle=0x80cd378,data=0x807e520,maxlen=32768,lenp=0xbffff4b0)

  [dll] control_option(handle=0x80cd378,option=11,action=0,value=0xbfffeb68,info=(nil))

  [dll] control_option(handle=0x80cd378,option=12,action=0,value=0xbfffeb68,info=(nil))
  Speicherzugriffsfehler

  The pnm backend passes the test both in direct mode and over the net.

  Bye, Henning
