Michel,
What kind of connection (modem, Ethernet, carrier pigeon)? What
kind of remote host (o/s, version, that stuff)?
If the comms link is broken, or appears to be to K95/Win95 then
nothing goes out on that link. TCP/IP sends nothing if nothing needs
sending, to coin a phrase, with the exception that some hosts may emit
keep-alive probes on inactive links. Keep-alive timeouts vary wildly.
In the meanwhile the Unix side has a valid connection because nothing
has occurred to test it.
Ensure the machine's power-saving feature are turned off because
when saving starts (the power is being saved) comms are kaput.
Triple check your flow control settings, if using a serial port.
TCP/IP can't deal with XON/XOFF flow control and thus you need to use
RTS/CTS ("hardware") flow control to a modem. That's controlled by Windows.
Also, please note that some versions of Linux, if that's your remote
host, lose their ARP cache entries after some time and thus do not know
how to respond to a client.
And, ensure no other machine is using your IP address, because it
will block further traffic from your machine on that link.
Finally, what might be meant specifically by "kicked out"? That
and your taskbar etc comments are important clues and we need to have them
clarified.
