we have an issue on setting the COM Index in registry for Serial1..4 on a PicoMOD7. (HW V1.0, Kernel 1.09, NBoot VN20, Bootloader 1.14)
E.g. if we change "Index" from 3 to 5 for \Drivers\BuiltIn\Serial3 and we do a "reg save", after a reboot there is still the old setting with "Index" 3.
This behaviour is the same on Serial1. --> change "Index" from 2 to 5 --> "reg save" --> reboot --> "Index" 2.
On PicoMOD6 /(WIN CE 6) we did something similar by changing Serial2 from Index 2 to 5 and it worked.
We have to use this because our USB Martel Printer doesn''t work anymore on PicoMOD7.
As far as we understand the Virtual COM-Port driver of this printer takes first available and free COM-Port of the Windows system.
How do we have to change the Index Values on the PcioMOD7 registry?
