</div></div>Hi Mike,<br>
<br>
I've seen this before, it's probably a file permissions problem with<br>
the serial ports files in /dev/*. Check the log files for error messages<br>
associated with attempting to access the serial port in question (dmesg<br>
| grep tty should do the trick).<br>
<br>
Try using the port while running D-RATS as root. If that works, it's a<br>
permissions problem.<br>

Also try entering: ls -l /dev/tty*<br>
That will show who "owns" the serial ports (the /dev/ttyS*<br>
and /dev/ttyUSB* files). On my Fedora 14 system, those files are owned<br>
by user root:dialout. The dialout group has read/write access to the<br>
ports, so I added myself to that group. In F11 or 12 it was group tty,<br>
in another release it was uucp.<br></blockquote><div><br><b>Same here, ttyUSB0 was owned by root:dialout.

<br>
I've had to add my username to additional groups after several upgrades<br>
to regain access to the SERIAL and/or USB ports. I'm running Fedora 14<br>
here now, and a quick check using SYSTEM-> Administration->Users and<br>
Groups shows that I've added myself to the following groups:<br>
dialout<br>
tty<br>
uucp<br>
<br>
After adding yourself to those groups you will need to logout and log<br>
back in for the change to affect.<br>
<br>
Hope this helps!<br>
