Here is the mac mini stderr from: chartread -D5 sam-clp-315-rgb-196 Read strips A-D no problem. On strip E, I momentarily triggered the device and I got "failed due to communication problem". After that, the only thing I could do was quit. Triggering the device a second or third time did nothing. Note: this is an EASY thing to do!!! -- Rick Richardson rick.richardson@xxxxxxxxxxx http://home.comcast.net/~rickrich1/ Linux printer driver for HP CLJ 2600n http://foo2hp.rkkda.com/ Linux printer driver (KM 2430 and HP 10xx) http://foo2zjs.rkkda.com/ Linux tools for geocaching http://geo.rkkda.com/
