Error Script to send serial commands over ethernet
Hi there,

I have a Debian server (192.168.1.1) connected through ethernet to a RS232 device servers (192.168.1.5) that is then connected through RS232 to a Video Projector.

The idea is that I want to send commands to the video projector (eg. turn on/off) via the device server.

According to the Benq Video Projector Manual, the command to read the power status is :
Code:
<CR>*pow=?#<CR>

The Moxa NPort 5150 Manual tells me to use port 4001 for communication.

All right then...

How do I send my command?

I tried
Code:
root@arcturus:~# telnet 192.168.1.5 4001
Trying 192.168.1.5...
telnet: Unable to connect to remote host: Connection refused
root@arcturus:~# echo -e '\r*pow=?#\r' | netcat 192.168.1.5 4001
(UNKNOWN) [192.168.1.5] 4001 (?) : Connection refused

Do you have any idea on how I should do that?

== edit start =========================
I found out that if I use UDP mode, the connection is accepted but freezes.
I have to press Ctrl+C to return to tty:
Code:
root@arcturus:~# echo -en '\r*pow=?#\r' | netcat -n -v -u -o /tmp/hextraffic.dump 192.168.1.5 4001
(UNKNOWN) [192.168.1.5] 4001 (?) open
^C sent 9, rcvd 0

== edit end ===========================



Regards
Santiago
