Roy, When $ sudo modprobe agrmodem $ sudo modprobe agrserial there is dynamically created the port $ ls -l /dev/ttyAGS3 crw-rw---- 1 root dialout 62, 67 2008-02-11 22:31 /dev/ttyAGS3 which is not read-writeable as is by an ordinary user. $ sudo chmod a+rw /dev/ttyAGS3 does the desired change $ ls -l /dev/ttyAGS3 crw-rw-rw- 1 root dialout 62, 67 2008-02-11 22:31 /dev/ttyAGS3 is now read-write to all. This can only be achieved automatically, by including the chmod a+rw /dev/ttyAGS3 in some bootup script. I'll work one out for you by the weekend. Am very busy with all day meetings and travel till then. MarvS On Feb 11, 2008 5:59 PM, Roy Taylor <crt@xxxxxxxxxx> wrote: > Sorry, folks, I'm behind in my list reading.
