3The current drive status is displayed if the dim-network is online
4and the drivectrl has connection to cosy.

6The backround colors have the following meaning:
7<ul class='help'>
8<li>Drive is tracking</li>
9<li>Drive is tracking and the control deviation is larger than one arc-minute</li>
10<li>Drive is tracking and the control deviation is larger than two arc-minutes or the drive is in ERROR state</li>
11<li>Drive is offline, or online and neither moving nor tracking</li>
12<li>Drive is moving</li>
13</ul>

15If the drive is online, the current pointing position is displayed. Between
16sun-rise and sun-set a sun-symbol (&#9788;) is displayed. If between
17sun-set and sun-rise the moon is above horizon, a moon-symbol (&#9790;)
18is displayed. During tracking the current control deviation is
19displayed behin a plus-minus symbol (&plusmn;). If the source name of
20the current tracking position is available it is displayed in []-parenthesis.
21If the drive is currently moving a moving-symbol (&#10227;) is displayed.
22
23If the drive is online and in error state this is also indicated by the
24extension [ERR]. This should make it easier to detect this state.
25
26If the drive is switched off and either the sun- or the moon-symbol is
27visible, it is extended with either the time until sun-set (indicated
28with a down-arrow &darr;) or the moon disk visibility in percent.
29When the drive is switched on, this information is omitted due to space
30reasons.
31
32The &otimes;-symbol means that the drive is locked.

34More detailed informations about the sun and moon can be found at the
35weather page. More detailed tracking and pointing information at the
