Are the chips in those converters able to recognize if they're connected to a bidirectional device, and block reads if they aren't? The converter I'm using is ieee1284 capable. If the chip in that converter can't recognize if the connected device is bidirectional or not, then I'm thinking it's better to allow reads in case the device is bidirectional > > > Since I wasn't sure if dev=/dev/usb/lp0 would be processed, I created > > a softlink linking /dev/usb/lp0 to /dev/lp1, > > The speakup module does not read /dev, it uses the tty names. > > Could you tell us the content of /proc/tty/drivers? /dev/tty /dev/tty 5 0 system:/dev/tty /dev/console /dev/console 5 1 system:console /dev/ptmx /dev/ptmx 5 2 system /dev/vc/0 /dev/vc/0 4 0 system:vtmaster serial /dev/ttyS 4 64-95 serial pty_slave /dev/pts 136 0-1048575 pty:slave pty_master /dev/ptm 128 0-1048575 pty:master unknown /dev/tty 4 1-63 console Greg -- web site: http://www.gregn.net gpg public key: http://www.gregn.net/pubkey.asc skype: gregn1 (authorization required, add me to your contacts list first) If we haven't been in touch before, e-mail me before adding me to your contacts. -- Free domains: http://www.eu.org/ or mail dns-manager@xxxxxx _______________________________________________ Speakup mailing list Speakup@xxxxxxxxxxxxxxxxx http://linux-speakup.org/cgi-bin/mailman/listinfo/speakup
