My 4x1 DiSEqC switch is responding for both committed and uncomitted switch commands

Hi

I am having a DIGIWAVE GD-41A DiSEqC 4x1 switch, i am using the following DiSEqC message to select the switch position, for the below message switch is working properly.

Position Message
1 e0 10 38 c0
2 e0 10 38 c4
3 e0 10 38 c8
4 e0 10 38 cc

I found that switch selection is working properly even i change my command byte as 39 (uncommitted switch), i don't know whether this behavior is correct or not.

Also i having one DIGIWAVE DGS-SW8x1 switch i am using following DiSEqC message to select the position

Position Message
1 e0 10 39 70
2 e0 10 39 71
3 e0 10 39 72
4 e0 10 39 73
5 e0 10 39 74
6 e0 10 39 75
7 e0 10 39 76
8 e0 10 39 77

For these command my 8x1 switch is working fine.

But the interesting thing is, if connect a 4x1 switch in DiSEqC bus and i send the below messages position 2 is selected in 4x1 switch.

e0 10 39 74
e0 10 39 75
e0 10 39 76
e0 10 39 77

Can some one tell whether this behavior is correct or not.

I am writing a software for DiSEqC 1.2 support, while testing my software i found this behavior.
