telnet through com port

[Guest]

Is it possible to telnet through a com port and if so, how do I do it?

I tried telnet com1, but the connection failed. If that's the way you do
it, then I guess my device doesn't support a telnet connection through it's
com port.

Telnet is an internet utility, it will use whatever TCP/IP stack is on
your machine to communicate. If that stack is configured to use your
com1 port, then the communication will go that way, but it will always
be TCP/IP regardless of the hardware it's traveling over.

I don't know what it is you're trying to accomplish, but I suspect you
need to try something other then telnet.

I have a device to sync our clock system in our plant to our network time.
Somehow the device has been assigned a subnet mask of 255.2555.255.255
making it so I am unable to access it through it's IP address (ethernet
port). I have a utility that can read it's settings through a com port, but
it can't change them. The only way to change the settings is by telnet'ing
to it.

Any ideas on how to access a device that has a subnet mask of
255.255.255.255? Unforunately, the company that built it, didn't think to
put a reset button on it. :-(

You can use Hyperterminal instead of telnet, but I've found that the
Hyperterminal versions that ship with Win2K/XP do not transmit some
F-key presses used in some devices. If you run into that sort of thing
get a copy of Hyperterminal from a Win98 box.

Could you not "join" the same subnet by changing the mask to be the same?

Try using the HyperTerminal program that comes with Windows to open
the COM port directly. Hyperterminal is in your Accessories folder.
When you run Hyperterminal, create a new connection and then have it
open the COM port directly instead of opening a modem connection.
