I have tried the "ata" command again and pressed "enter" once, the reply from the device is "No carrier"... Is there anything else i can try to connect the two devices by using the ATC command mode ? > Hans Adams wrote: > ------------------------------------ > Hi, > Yes i know that i have to press "enter" only once after the "ata" command, i did so. > I will focus on this and try again. > Yes i know the correct way to enter values for specific registers, the "?" mark is used to read the register value, to verify if the correct value was saved.

Note that, on command line, there will be no response message (you should avoid entering "ata" command more than one time). Next, you can setting configuration for client device.
