You need this patch because your ASCOM does not accept an activation request after it issued a deactivation request, as opposed to the NT the german telco supplied. Both NTs seem to issue the deactivation request if layer2 is not activated some time after layer1. So I suggested to delay activation of layer1 until it is needed and to initialize (i. e. send a TEI request) right after layer1 is up. This is the effect of the patch I sent to you--at the cost of an extra wait of 2 seconds. For the time being don't expect that patch to be integrated into i4b. But, if Hellmuth agrees, the initialization of all layers will be delayed until triggered from userland. If this is done, you won't need the patch anymore--and the SMP people won't need their workaround.
