Hello Pat,

Please send the results as your user account of  these commands in
Terminal before doing any chmod:

groups

ls -l /dev/ttyUSB0

Then do your chmod command - send the command as well, and send the
results of ls -l /dev/ttyUSB0  again.

See if we can figure out  what is going on.
Thank you,

I have added myself to the dialout group, but I still need to manually do a chmod on /dev/ttyUSB0 in order to avoid the permissions error.  It is not a big problem to do this, but I thought that if I were in the dialout group, that would allow me to use the serial port without the chmod.  Can anybody tell me what might be going on?
