PCI express Startech PEX4S553B 4 port RS232 [9710:9904]: will work or not? (Debian11 64bits)
by floppy_stuttgart from LinuxQuestions.org on (#5NVW4)
Hello,
I bought that PCI card because I wanted to connect few older RS232 devices (printer, modem).
An error come at boot. See below.
It will work? or not? or partially? I am not use to analyse such messages. Or perhaps how to test such an RS232 card in the PC?
For the reason I have several things to debug, I would like to be sure it would work. If not, I will buy another one and not spend more time in debugging something which could obviously not work.
If the signs are this card is not good at all, any advice what hardware PCI-express I should use (2x RS232 output) is welcome (PC HP600G4 SFF).
Remarks or any recommendations are highly welcome.
Kernel from Debian11.
uname -r
5.10.0-8-amd64
