[sane-devel] Problems with mustek_pp and releasing the parallel port

[Jim George]

Eddy,

Without inetd...
scanimage hung and when I ctrl-c'd out of scanimage I get the following

"scanimage: received signal 2
 scanimage: trying to stop scanner "

saned did not quit.  When I killed it, the saned window showed these last
few lines

"[saned] do_scan: read 0 bytes from scanner
[saned] do_scan: status = `End of file reached'
[saned] do_scan: statuscode `End of file reached' was added to buffer
[saned] do_scan: select_fd was closed --> EOF

and scanimage window showed

"scanimage: received signal 13
scanimage: aborting"

without inetd running but with gdb.........


scanimage hung and when I crtl-c'd out I get the following
"scanimage: received signal 2
scanimage: trying to stop scanner"

saned didn't quit.  When I pressed ctrl-c in gdb I got
"[saned] do_scan: select_fd was closed --> EOF

Program received signal SIGINT, Interrupt.
0x4027786d in sanei_debug_sanei_pa4s2_call ()
   from /usr/lib/sane/libsane-mustek_pp.so.1 "

I then did 'bt' and got
"#0  0x4027786d in sanei_debug_sanei_pa4s2_call ()

I hope this helps.
