Pinging a port?

Is there a way of pinging a port behind a device? I am not sure if our servers even allow this, but I am curious if I can ping a port...

I know i can ping an IP like... ping 192.168.1.1, I can even access the server interface at http://192.168.1.1

There is a device behind 192.168.1.1 which is on port 1001, so to access this device I can use a web interface simply by going http://192.168.1.1:1001 and it should come up. These IP's and ports are not the actual ones we use BTW, not that it matters.

So how can I ping the device at 192.168.1.1:1001?

FYI, the IP would be our server, and the device on the port is a DSL modem in one of the rooms, I have one in particular I am trying to reach, it is able to recieve information but not send it - it would seem. I would like to remotely reboot the device, but I cannot tell if it's actually plugged in or not. Or at least try to trick it into working again.:D

    PING uses ICMP which is not a TCP based protocol. It simply tells whether or not a host at a specific IP address replies or not. To actually determine if TCP/UDP (Transport Layer) ports are open, you'll have to use a port scanner of some sort. Do a google search for an application called nmap. It shoud be able to help.
