How can I attach a serial console on USB port

[Michel Lavezzi]

FreeNas 9.1.1 64 bits
My system board doesn't have a serial port, and I want to use a serial console.
I bought USB / Serial adapters: 1 for freeNAS, 1 for my laptop, a serial cable, connect all of that in the correct order.
I installed Hyperterminal on my laptop (windows 7 32 bit)
I configured FreeNas to use console thru serial console,
and nothing works.
Seems Freenas doesn't use the right port, but how to know which port to use, how to change it ?

Thanks in advance for your help.

I could be wrong but I don't think FreeNAS includes USB->Serial adapter drivers, so you'd have to add the driver yourself(assuming a FreeBSD driver exists for your hardware).

I only have drivers for Redhat 7.3, 8 and 9
I don't think they could work.
and I don't know how to compile and install them.
Too bad ...

They won't work. That's Linux. This is FreeBSD.

99% (or whereabout) of cheap (and more expensive) serial-usb adapters commonly found on ebay for less than $10 are using a prolific PL2303 controller. The OP should check what chipset is used by his USB/Serial adapter..

FreeBSD has supported those for over 10 years with the uplcom driver... so you'll need to find the ko module for it and load it in freenas

uplcom is included directly in the FreeNAS kernel, no need to look for .ko modules. Actually, all these are included:
