C# Remoting to access SerialPort?

I'm having problems with the telnet on a device, so wanting to run a program attached by serial port to the device and then have other machines access this by C# remoting. However, I can't seem to find a way to give the interface access to this local resource after setting it up?

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using System.Net;
using System.IO;
using System.IO.Ports;

namespace C7_Serial_Server
{
        class C7_Serial
        {
                internal static SerialPort SP { get; set; }

                static void Main(string[] args)
                {
                        Console.Write("Serial port: ");
                        int SP_Location = Convert.ToInt32(Console.ReadLine());

                        SP = new SerialPort("COM" + SP_Location);
                        SP.BaudRate = 57600;
                        SP.Open();

                        AcceptConnections();
                }

                static void AcceptConnections()
                {
                        HttpServerChannel tcpChannel = new HttpServerChannel(9996);
                        ChannelServices.RegisterChannel(tcpChannel, false);

                        Type commonInterfaceType = Type.GetType("C7_Serial_Server.Access");

                        RemotingConfiguration.RegisterWellKnownServiceType(commonInterfaceType, "C7_Serial_Access", WellKnownObjectMode.SingleCall);
                        RemotingConfiguration.CustomErrorsMode = CustomErrorsModes.Off;
                }
        }

        public interface SetProfile
        {
                Access.Info C7_SetProfile(Access.Setup Location);
        }

        public class Access : MarshalByRefObject, GetStats, SetProfile
        {
                

                [Serializable]
                public class Info
                {
                        public string Equipment { get; set; }

                        public Info(string Equipment)
                        {
                                this.Equipment = Equipment;
                        }
                }

                [Serializable]
                public class Setup
                {
                        public int Slot { get; set; }

                        public Setup(int Slot)
                        {
                                this.Slot = Slot;
                        }
                }

                public Info C7_SetProfile(Setup Location)
                {
                        return new Info("Set");
                }
        }
}

I need the "SetProfile" command to access the serial port created by the console program, how is the best way to do this?

Thanks!
