Thanks for the reply! Yes, there is no such module built: /usr/src/linux-6.1.106-Unraid# cat .config | grep PARPO CONFIG_ARCH_MIGHT_HAVE_PC_PARPORT=y CONFIG_PARPORT=y CONFIG_PARPORT_PC=y # CONFIG_PARPORT_SERIAL is not set CONFIG_PARPORT_PC_FIFO=y # CONFIG_PARPORT_PC_SUPERIO is not set # CONFIG_PARPORT_AX88796 is not set # CONFIG_PARPORT_1284 is not set # CONFIG_I2C_PARPORT is not set # CONFIG_PPS_CLIENT_PARPORT is not set /usr/src/linux-6.1.106-Unraid# modprobe parport_serial modprobe: FATAL: Module parport_serial not found in directory /lib/modules/6.1.106-Unraid Is there a way to build anything on the Unraid system? Or should I set up a VM with Gentoo or Slackware with the same kernel to build it and transfer to the server?

Hello all, I am new here and recently built an Unraid server. Everything is good but one thing: I have a cheap PCI-E card with 2 COM and 1 Parallel ports and can't figure out how to use it. I need just one COM port from it. The card is detected by the system: #lspci -v ... 02:00.0 Serial controller: Nanjing Qinheng Microelectronics Co., Ltd. CH384 Dual Port Serial and Parallel Port Adapter (rev 10) (prog-if 05 [16850]) Subsystem: Nanjing Qinheng Microelectronics Co., Ltd. CH384 Dual Port Serial and Parallel Port Adapter Flags: fast devsel, IRQ 255, IOMMU group 13 I/O ports at 4000 [disabled] [size=256] Memory at 70800000 (32-bit, prefetchable) [disabled] [size=32K] I/O ports at 4100 [disabled] [size=4] Expansion ROM at 74200000 [disabled] [size=32K] Capabilities: [60] Power Management version 3 Capabilities: [68] MSI: Enable- Count=1/32 Maskable+ 64bit+ Capabilities: [80] Express Legacy Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting ... I also see the following in the dmesg: # dmesg | grep ttyS [ 0.299290] serial8250: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A but I don't know if it is about this card. Probably not. I found this driver from the chip vendor: https://github.com/WCHSoftGroup/ch35_38x_linux but it seems to be impossible to build a custom driver on the Unraid system. The page mentions that the chip should be supported by 8250_pci driver, but it is listed under "Unused" on the Unraid UI Could any one help or give a direction to dig? 😃 Thank you. P.S. I am sorry if this topic is a duplicate but I couldn't find anything related via search...
