I found this and am using it as my base, but it wasn't working right out of the box. My goal is also to treat it as a package instead of a command line utility, so my code changes will reflect that.

class Netcat:
    def __init__(self, hostname, port):
        self.hostname = hostname
        self.port = port
    def send(self, content):
        self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.socket.connect((self.hostname, self.port))
        self.socket.setblocking(0)
        result = '';
        read_ready, write_ready, in_error = select.select([self.socket], [], [self.socket], 5)
        if(self.socket.sendall(content) != None):
            return
        while(1):
            buffer = ''
            try:                
                buffer = self.socket.recv(128)
                while(buffer != ''):
                    result += buffer
                    try:
                        buffer = self.socket.recv(128)
                    except socket.error as err:
                        print (err, type(err))
                        buffer = ''
                if(buffer == ''):
                    break
            except socket.error as err:
                print (err, type(err))
            if(buffer == ''):
                break
        return result

When I send a basic command to my device, it returns the following.

50PMA-019 Connection Open
Atten #1 = 63dB

My code reads the first line, but then I get an error saying that the connection is temporarily unavailable and it does not get the second line. If I change it to blocking, it just blocks and never returns. Any thoughts?

python netcat
