Read line of ASCII string data from remote host over TCP/IP
Write and Read Line of ASCII Data from Remote Host
Create a TCP/IP client connection called
t, connecting to a TCP/IP echo server with port 4000. To do so, you must have an
echotcpip server running on port 4000.
echotcpip("on",4000) t = tcpclient("localhost",4000)
t = tcpclient with properties: Address: 'localhost' Port: 4000 NumBytesAvailable: 0 Show all properties, functions
Check the default ASCII terminator.
ans = "LF"
Set the terminator to
"CR" and write a string of ASCII data. The
writeline function automatically appends the terminator to the data.
Write another string of ASCII data with the terminator automatically appended.
Since the client is connected to an echo server, the data you write to the server is returned to the client. Read a string of ASCII data. The
readline function returns data until it reaches a terminator.
ans = "hello"
Read a string of ASCII data again to return the second string that you wrote.
ans = "world"
Close the echo server and clear the TCP/IP client connection.
echotcpip("off") clear t
t — TCP/IP client
TCP/IP client, specified as a
readline(t) reads ASCII data from the remote host
specified by the TCP/IP client
