How to use It about telnet HOT 1 CLOSED

There's a readme on the homepage https://github.com/9swampy/Telnet and a test suite in the download. Should be enough.

using (Client client = new Client(server.IPAddress.ToString(), server.Port, new System.Threading.CancellationToken()))
{
client.IsConnected.Should().Be(true);
(await client.TryLoginAsync("username", "password", TimeoutMs)).Should().Be(true);
client.WriteLine("show statistic wan2");
string s = await client.TerminatedReadAsync(">", TimeSpan.FromMilliseconds(TimeoutMs));
s.Should().Contain(">");
s.Should().Contain("WAN2");
Regex regEx = new Regex("(?!WAN2 total TX: )([0-9.])(?! GB ,RX: )([0-9.])(?= GB)");
regEx.IsMatch(s).Should().Be(true);
MatchCollection matches = regEx.Matches(s);
decimal tx = decimal.Parse(matches[0].Value);
decimal rx = decimal.Parse(matches[1].Value);
(tx + rx).Should().BeLessThan(50);
}
