TCP Socket Send Byte and Receive Byte

Demonstrates the Chilkat Socket ReceiveByte and SendByte method. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$sock = New-Object Chilkat.Socket

# --------------------------------------------------------------------
# This example uses the public TCP echo service at https://tcpbin.com/
# --------------------------------------------------------------------

$useTls = $false
$port = 4242
$maxWaitMs = 5000
$success = $sock.Connect("tcpbin.com",$port,$useTls,$maxWaitMs)
if ($success -eq $false) {
    $($sock.LastErrorText)
    exit
}

# Wait a max of 2 seconds for a response..
$sock.MaxReadIdleMs = 2000

# Send a byte.
$sock.SendByte(96)

# The tcpbin.com echo server only echoes after receiving an LF (linefeed char)
$sock.SendByte(10)

# The echo server will echo back whatever is sent to it.
# We should be able to read the same byte back..
# After successfully reading, the byte value is available in the ReceivedInt property.
$treatAsUnsignedInt = $true
$success = $sock.ReceiveByte($treatAsUnsignedInt)
if ($success -eq $false) {
    $($sock.LastErrorText)
    exit
}

# Let's look at the value of the byte received.  It should be 96.
$($sock.ReceivedInt)

# The echo server also echoed the LF back.
$success = $sock.ReceiveByte($treatAsUnsignedInt)
# Assuming success..

# Should be decimal 10.
$($sock.ReceivedInt)
