How to install MOXA PCI card for two Serial Ports like CP-102U/UL

Jezekilj Monk · 01-18-2023, 10:59 AM

Hello,

Does anybody know how to properly install MOXA PCI card that provides two serial ports? On Ubuntu 22.04 or Linux Mint 21?

Basically I downloaded kernel driver from this link

https://www.moxa.com/getmedia/5f51c6...river-v5.1.tgz

which is on this web page

https://www.moxa.com/en/support/search?psid=56531

and tried to follow instructions in readme.txt file for static serial ports and got stuck at the step 3.5.6

In some of the previous steps I had to adjust proper paths as well, but this was not too complicated.

Post output of lspci -v
Which kernel is in use?

This card (2-port RS-232 via PCI) should run out of the box if your kernel has compiled in or as modules:

"8250/16550 and compatible serial support" aka CONFIG_SERIAL_8250
"8250/16550 PCI device support" aka CONFIG_SERIAL_8250_PCI
"Maximum number of 8250/16550 serial ports" aka CONFIG_SERIAL_8250_NR_UARTS with a value of ≥ 2; value should be equal or larger to number of all RS232 ports in your computer
"Number of 8250/16550 serial ports to register at runtime" aka CONFIG_SERIAL_8250_RUNTIME_UARTS with a value equal to "Maximum number of 8250/16550 serial ports"

I hoped it would work out of the box after fresh install of linux mint 21.1, but it didn't
