rs232 to ethernet

Although USB to Ethernet adaptors are cheap and plentiful, Mac OS X drivers are not.

USB-to-Ethernet offers you USB to Ethernet Adaptor Drivers.
There are two basic catagories of USB-To-Ethernet adaptors:
· USB 1.1 devices that use a Pegasus driver.
· USB 2.0 devices that use a AX8817x driver (or its successor, the AX88772).


Each disk image includes an installer for Panther or Tiger, and a "src" folder containing the corresponding xCode projects.

Installation

Download and mount the appropriate driver disk image listed above, run the corresponding installer for Panther or Tiger, and then restart your system as suggested. The Installer will ask you to authenticate so it can place the corresponding driver in "/System/Library/Extensions/" with the correct file permisions to load as a kernel extension.

Next, plug-in your Ethernet adaptor with a live Ethernet cable attached. When you open the Network Preferences panel, it should inform you that a new port has appeared and ask if you want to enable it. Enable the new port and apply your network settings. Thats it.

Each driver is pre-configured to recognize a handfull of common devices. If your device does not appear to be recognized by the driver, you might have to add it to the Info.plist file, which is located inside the USBPegasusEthernet.kext or USBAx8817x.kext directory. You can use the System Profiler or USBProber tool to find the corresponding Product ID and Vendor ID.

To uninstall the driver, make sure any USB adaptors are disconnected, and then drag the corresponding driver in /System/Library/Extensions/ USBPegaususEthernet.kext or USBAx8817x.kext to the trash. You may need to authenticate that you have administrator privileges.

USB 1.1 Performance

The Pegasus chipset provides a USB 1.1 compatible implementation which could be a concern for some users. USB 1.1 runs at 1.5 Mbps (low speed) or 12 Mbps (full speed). For best performance, its important to isolate any low speed devices on a separate bus. Mice and keyboards often run at low speed.

Using the Link Rate tool in IPNetMonitorX, I measured the link rate to another device on my LAN as 6 Mbps. The built-in Ethernet on my 12" PBG4 reported 44 Mpbs. When I measured the link rate to the next hop router through my cable modem, it reported 1 mbps. It didnt make any difference whether I used Ethernet built-in or the USB-To-Ethernet adaptor. Finally, I downloaded a 2.2 MB file to compare the throughput using the Monitor tool.

Both downloads took 5 seconds, but Ethernet built-in reached a peak rate of 589 KBps versus 579 kBps. Repeating the experiment several times produced similar results. Ethernet built-in might be 1-2% faster, but performance was clearly limited by the speed of my cable modem (Your Mileage May Vary).

USB 2.0 Performance

The AX8817x chip set provides a USB 2.0 compatible implementation which runs at up to 480 Mbps (high speed), so it should be possible to keep up with 100 Mbps fast ethernet as long as there are no other slower devices on the same bus. To test this I copied a 64.8 MB music file to my PBG4 laptop connected through a LinkSys USB200M Ethernet Adaptor (en3) and compared this to the same file transfer using Built-in Ethernet (en0).

Both transfers reached 10 MBps (80-90 Mbps) and took about 10 seconds. I repeated the test in the other direction.

While the USB-To-Ethernet adaptor was slightly slower, at 80 Mbps there was little noticeable difference. Files moved quickly from one system to another via 100 Mbps fast Ethernet. Copying the same file using AirPort wireless took 50-90 seconds.

Stability

While other USB-To-Ethernet drivers are reported to be buggy, I havent encountered any stability problems to date. The adaptor turns off when the computer goes to sleep and comes back on when the computer awakes. It does not support "Wake On LAN" at this time.

Wrap Up

This USB-To-Ethernet Adaptor combination could be an attractive solution for a Mac Mini, or old iBook used as an Internet gateway or server. Im particularly fond of using old laptops as servers since they are compact, quiet, use little energy, and include their own battery backup.

NetPacket::Ethernet is a Perl module to assemble and disassemble ethernet packets.

SYNOPSIS

use NetPacket::Ethernet;

$eth_obj = NetPacket::Ethernet->decode($raw_pkt);
$eth_pkt = NetPacket::Ethernet->encode(params...); # Not implemented
$eth_data = NetPacket::Ethernet::strip($raw_pkt);

NetPacket::Ethernet provides a set of routines for assembling and disassembling packets using the Ethernet protocol.

USB to Ethernet Connector lets you connect to any USB device located on a remote PC on a local network or the Internet. You will be able to work with it as with a local USB device and applications working with it wont even see the difference. USB to Ethernet Connector works with a USB driver at the system level. It intercepts USB port activity for the shared device and redirects it via TCP/IP to a remote site, where it is handled appropriately. To achieve such functionality, USB to Ethernet Connector is installed on both computers that take part in the communication process. Therefore, USB to Ethernet uses client-server architecture (server side has the USB device physically attached to it, while client side connects to remote server and uses the services it provides), but each side can be a client and a server at the same time. USB to Ethernet Connector shares USB ports rather than devices. The benefit of this approach is that you may plug in a USB device, connect to it from the remote host, detach the device and plug in another one, and it will automatically appear at the client side. Among its key-features are an unlimited number of USB devices that can be shared, auto-connecting to new USB devices whenever you plug them in and working with virtual machines. Shared USB ports are also automatically re-configured every time you boot your PC. The program is fully compatible with Windows 2000/XP/2003 and with HyperThreaded and multi-processor systems. An advanced and robust architecture, a wide range of supported USB devices and standards, and the simplicity of use make USB to Ethernet Connector a real pleasure to work with.

Serial to Ethernet Connector is an advanced software solution developed to share serial port devices over TCP/IP network. Thus, any serial port device connected to COM port at local PC could be accessed from anywhere in the world via internet, for example. When the attached serial port device sends communication data it will be actually transmitted over TCP/IP network. Such behavior is achieved due to the use of virtual serial port technology which emulates standard COM ports. In that case Windows OS treats virtual serial ports in the same way as real ones therefore you are no longer limited to just two real ports (any number of physical ports you have) per system and may create COM port connections without occupying any real serial port. Formerly known as VSPD.Net, Serial to Ethernet Connector has a completely new interface and greatly revamped engine. It allows you to use three different types to connect to remote computer. The first type is port-to-port connection, which lets you connect two computers through TCP/IP network. In this way you can emulate virtual null-modem cable connection. Serial to Ethernet Connector allows you to customize remote serial port settings locally or dynamically fetch these settings from the remote end. Second type is the port-to-TCP client, which allows you to connect to remote server and send/receive communication serial data over TCP/IP network. Once connection is established, all data sent from remote serial port device, attached to the server, will be genuinely delivered to local serial port where it can be further processed. The last type is the port-to-TCP server which allows you establish multiple connections to local serial port device and redistribute COM port device data all over the world. Server listens to all incoming connections at the defined TCP port and redirects input/output serial data to TCP/IP network. Serial to Ethernet Connector can be easily configured for current demands.
