This port is detected and I can 'cat' it (no 'safety check engaged'). It seems this port is not usuable for a baycom modem though. I verified that the baycom modem works fine on an other system. On this system it doesn't work; it doesn't "see" that the system sends data. So for that I added a PCI-E serial port adapter: 02:00.0 Serial controller: NetMos Technology Device 9904 (prog-if 02 [16550]) Subsystem: Device a000:1000 Flags: fast devsel, IRQ 24 I/O ports at d480 [size=3D8] Memory at fe9f9000 (32-bit, non-prefetchable) [size=3D4K] Memory at fe9f8000 (32-bit, non-prefetchable) [size=3D4K] Capabilities: [50] MSI: Enable- Count=3D1/8 Maskable- 64bit+ Capabilities: [78] Power Management version 3 Capabilities: [80] Express Legacy Endpoint, MSI 00 02:00.1 Serial controller: NetMos Technology Device 9904 (prog-if 02 [16550]) Subsystem: Device a000:1000 Flags: fast devsel, IRQ 25 I/O ports at d800 [size=3D8] Memory at fe9fb000 (32-bit, non-prefetchable) [size=3D4K] Memory at fe9fa000 (32-bit, non-prefetchable) [size=3D4K] Capabilities: [50] MSI: Enable- Count=3D1/8 Maskable- 64bit+ Capabilities: [78] Power Management version 3 Capabilities: [80] Express Legacy Endpoint, MSI 00 02:00.2 Serial controller: NetMos Technology Device 9904 (prog-if 02 [16550]) Subsystem: Device a000:1000 Flags: fast devsel, IRQ 26 I/O ports at d880 [size=3D8] Memory at fe9fd000 (32-bit, non-prefetchable) [size=3D4K] Memory at fe9fc000 (32-bit, non-prefetchable) [size=3D4K] Capabilities: [50] MSI: Enable- Count=3D1/8 Maskable- 64bit+ Capabilities: [78] Power Management version 3 Capabilities: [80] Express Legacy Endpoint, MSI 00 02:00.3 Serial controller: NetMos Technology Device 9904 (prog-if 02 [16550]) Subsystem: Device a000:1000 Flags: fast devsel, IRQ 27 I/O ports at dc00 [size=3D8] Memory at fe9ff000 (32-bit, non-prefetchable) [size=3D4K] Memory at fe9fe000 (32-bit, non-prefetchable) [size=3D4K] Capabilities: [50] MSI: Enable- Count=3D1/8 Maskable- 64bit+ Capabilities: [78] Power Management version 3 Capabilities: [80] Express Legacy Endpoint, MSI 00 Problem now is: it is detected but no serial ports are "created".
