Thomas Kocourek: ... All went well and I got the file ok, but two side effects (no doubt due to my ignorance) - 1) cua3 became owned by the guest account with permissions set to 644 & 2) the bash shell did not die when he hung up the line. SO, 1) how do I prevent the guest account from owning the modem, and 2) how do I get bash to die when the line is hung up?
Bash seems to terminate properly for me... I wonder if your modem and cable deliver the right signals to your system. If the system never receives a signal from the modem that indicates it's hung-up, it won't know to do anything special. The easiest way I know of to check this out is to use the (unfortunately not quite free because "you're supposed to buy the book") kermit package. Kermit can be obtained by anonymous ftp from kermit.columbia.edu, as kermit/linux/kermit-190-5.deb. In kermit, you say something like: set line /dev/ttyS0 show comm The display should end with something like: Carrier Detect (CD): Off Dataset Ready (DSR): Off Clear To Send (CTS): Off Ring Indicator (RI): Off Data Terminal Ready (DTR): On Request to Send (RTS): On If it doesn't check your modem manual (and maybe check your cable). There's probably a way of checking the status of these lines using just a standard debian system, but I don't know what it is. -- Raul
