Serial PCIexpress question
Clash Royale CLAN TAG#URR8PPP
I am running RHEL6.10. I have a new Dell with a PCIexpress serial card installed. I cannot talk through the serial port via minicom. I also have a usb to serial converter that is working fine with minicom.
My username is included in the dialout group and permissions on the /dev/ttyS0 file are correct.
Does a third party driver for the serial card need to be installed for this PCI express serial card?

/dev/ttyS0is very likely the legacy device on the southbridge, which may or may not be connected on your motherboard. It's very likely not the PCIe serial card. Look throughdmesgafter boot to see if the serial card gets picked up, and if the kernel module (driver) for it loads. If not, you may need a kernel module for it. It would also help if you mentioned the exact brand and model of the serial card in the question, and include thelspci -nnline for it; then we can google for hardware information.

/dev/ttyS0is very likely the legacy device on the southbridge, which may or may not be connected on your motherboard. It's very likely not the PCIe serial card. Look throughdmesgafter boot to see if the serial card gets picked up, and if the kernel module (driver) for it loads. If not, you may need a kernel module for it. It would also help if you mentioned the exact brand and model of the serial card in the question, and include thelspci -nnline for it; then we can google for hardware information.

Look through dmesg after boot to see if the serial card gets picked up, and if the kernel module (driver) for it loads. If not, you may need a kernel module for it.
