Since you are using a COMPUTER , and NOT a DUMP TERMINAL , I think you should apply steps in the page : http://www.freebsddiary.org/serial-console.php As you know , "serial console" is a special hardware to communicate headless computers ( without keyboard and video terminal ) . Therefore , communication with a "serial console" and a "computer" are different concepts ( which I do not know exactly , but with respect to specifications , it seems like that ) . This means that , in the client computer ( as simulator of "serial console" ) , it is necessary to have a program to receive output inserted into serial port by the server , and display it for you like a "serial console" . If you use a USB port in the client and a converter from "serial-to-USB" , obviously , you need that your program should be able to manage USB port for that reason . I think management of USB port and RS 232 port are very different concepts ( approximately ) . These actions are performed by the "serial console" by itself . Myself , I will use two computers to simulate a "serial console" , because I asked price of a "serial console" , which come out as more than 800 Euro ( in Turkey ) . Thank you very much .
