serial modem connection
I configured the serial modem in my P6-550 AIX 5.3 box

But i dont have telephone line.
when I run the command
Code:
# cu -l /dev/tty1

the output is as follows
does it mean that my modem is responding to the command?
can i say my serial port is working and communicating fine?
Code:
Connected

Lost carrier.

The connection is ended.

  1. Use CODE-tags when displaying code, data or logs to enhance readability and keep formatting like indention etc. ty.
  2. You have now 3 threads here regarding your topics, serial adapter, serial adapter communication, modem communication. Next time that you have so similar topics tied to each other, try to stay in 1 or 2 threads and don't open up a new thread for every new question you have to the topic. Just add the new question on the old topic.
    Take this as a warning.

Perhaps try -m option with cu. Man page says:

Code:
       -m
            Instructs the cu command to ignore modem control signal data
            carrier detect (DCD).
