Thread: Enable RS232 serial port ubuntu

Hello good, I have a UPS that requires connection to a PC RS232 port for himself only configurarlo.Ahora I have a PC with Ubuntu and can not get funcione.He installed the manufacturer's page, but no communication through the serial port. Do you have to activate it somehow? Thank you.

That is, at one end the cable is a sub-d 9 and the other is an RJ45 (So much it costs to write properly?). If the computer is turned bios serial port, and this is not broken, with a 99% probabailidad the Linux kernel has detected and working. As you say that there is no communication through that port, and effects may help, it would be nice to share how you know there is communication through that port.But in detail, because a "no work" does not correspond to such a claim.

I do not use Ubuntu but this distro is characterized by including support for just about anything under the sun. Do not think you should do anything to have serial port support. At best, being somewhat older, non-plug & play is possible that the kernel module that provides support not loaded automatically. With the above command you load it. You can get more information on whether the serial port support is loaded and running looking at the system log the word "ttyS".
