Yes, indeed. I didn't notice this in my setup because the old config<br>
|
|
files used /dev/ttyS6 (which doesn't exist on my computer). But later<br>
|
|
.conf files use /dev/ttyS0 which does lead to large delays when no<br>
|
|
dc25/dc210 camera is attached. Can someone think of and implement a<br>
|
|
quick check whether a dc25/dc210 camera is attached? In the meantime,<br>
|
|
I'll comment out these backends from dll.conf.<br>
