mTCP is a suite containing several utilities, one of which is FTP. It is similar to the FTP client of various Windows, running in Command Prompt.

In order to install and use mTCP:

1. mTCP [ Home page ]

2. Packet driver for Ethernet network card:



3. Create a folder, for example C:\DRIVERS\. Put there: a packet driver for Ethernet network card.

4. Set up network. For example, by means of Microsoft Network Client 3.0 [ How-to page ]

5. Start packet driver. In the case discussed it is:


6. Unpack the archive with mTCP into a folder, C:\SOFT\MTCP for instance, and create a tcp.cfg file in it with the strings:



The value of PACKETINT - the interrupt number used in the packet driver starting. The value of HOSTNAME - any.

7. Start DHCP.EXE (DHCP will set up mTCP for work with the network):


8. Start FTP:

FTP [ FTP address / host ]

There will be a prompt for a name, after that - the password. Next, it is better to switch to passive mode:


[ The list of the main commands supported by FTP of mTCP is available in ftp.txt, included in mTCP suite archive ]

To exit:


mTCP - GNU GPL v3.

Arachne web browser. Installing and setting up for dial-up internet connection

A : Installing Arachne web browser on a disk created in RAM - Arachne runs the fastest this way. RAM size should allow for a RAM disk of 6 MB or more. In order to install and set up Arachne web browser for dial-up internet connection, there have to be several programs at hand: 1. Arachne web browser [ Download ] 2. If Arachne web browser is to be used for surfing web pages with character encoding other than Latin for West European languages, visit www.glennmcc.org/apm/ to find available character set packages and download the necessary one. 3. Mouse driver, mouse.com for instance [ Download ] 4. Archivers. For example, PKZIP [ Download ] and PKUNZIP [ Download ] 5. If it is not MS-DOS 6.0+ to be used, QEMM97 [ Download ] 6. If it is not MS-DOS 6.0+ to be used, TDSK [ Download ] Installing and setting up Arachne web browser, step by step: 1. Create a RAM disk. Which drive letter will be assigned to it comes from the assumption that A: and B: go to floppy drives (even if there is only one, both letters will be reserved anyway), C: goes to the first active primary MS-DOS partition on the first physical hard disk. If there are more disks, then there will be as many letters used consecutively as to name them all. Unless there are no devices installed using DRIVER.SYS or similar drivers, the next drive letter will be assigned to the RAM disk. In order to be sure, after having the relevant string for making RAM disk added to CONFIG.SYS (See below), computer could be restarted and what letter is assigned to the RAM disk checked by experiment. In this case, it is E: Depending on RAM size it needs to be decided how many megabytes can be reserved for RAM disk. Basically, the more the better. Since, for instance, web browser cache is going to swell during prolonged and intensive use within a session. In this example the RAM disk is 12 000 KB. The maximum size for RAMDRIVE.SYS MS-DOS driver is 32 767 KB, the one of TDSK - 64 MB. In order to create such a disk, the string has to be added somewhere in the middle of CONFIG.SYS as follows: DEVICE=C:\DOS\RAMDRIVE.SYS 12000 512 512 /E 2. Create a folder, for example C:\DRIVERS\. Put there a mouse driver, for instance mouse.com 3. Add a string starting mouse driver to AUTOEXEC.BAT. Specify there the full path to the driver, may be any: LH C:\DRIVERS\MOUSE.COM 4. Run MemMaker or OPTIMIZE from QEMM97 to optimize base memory management. If it is MemMaker, press Enter at any suggestion - MemMaker will handle it itself. Computer is going to restart several times, each time MemMaker will be re-running - again nothing, just Enter, is a safe choice. If it is QEMM97 (specifically OPTIMIZE), then there is going to be several restarts too and each time just pressing Enter is OK. 5. Start installation of Arachne web browser on RAM disk. In the case discussed it is E: A195GPL.EXE Press Y to continue: Press N to specify the path to the folder Arachne web browser is to be installed in: Specify the path to the folder Arachne web browser is to be installed in. In the case discussed it is E:\ARACHNE\.

JavaScript form submit

Submitting a form using JavaScript. A dropdown list (form + select + multiple options) is processed without any submit button. Example: --- Select a page --- Linux Windows DOS HTML / XHTML. Code: <form action="action.php" method="post"> <select name="page" required="required" onchange="this.form.submit()"> <option value="" selected="selected" disabled="disabled"> --- Select a page --- </option> <option value="http://www.kompx.com/en/os/linux-1.htm">Linux</option> <option value="http://www.kompx.com/en/os/windows-1.htm">Windows</option> <option value="http://www.kompx.com/en/os/dos-1.htm">DOS</option> </select> <noscript><input type="submit" value="Submit" /></noscript> </form> When an option has been chosen from the dropdown list, the form's state is changed. So the onchange event occurs and JavaScript code in onchange is executed: the process of the form submission in started by the script, not by clicking submit button which is absent. Some server-side script [ 3 ] is meant then to handle the form action. The script is supposed to get what the form sends and have it processed. A PHP script in action.php is used in the example: <?php if (isset($_POST["page"])) {     header("Location: $_POST[page]");     exit; } else {     echo "No options selected"; } $_POST is an array of variables passed to the current script via the HTTP POST method. So $_POST[page] contains the content of the value attribute in a select option. That is, a URL. It is passed from form to PHP script and the script redirects browser to the URL / page selected. HTML code of <noscript><input type="submit" value="Submit" /></noscript> is present in the form as a fallback in case JavaScript happens to be turned off. Then there is a submit button to appear and the form is usable anyway. [ 1 ] As well as Netscape 3.04+, Mozilla 0.6+. [ 2 ] As well as Netscape 3.04+, Mozilla 0.6+. [ 3 ] If a CMS is used, form action may be handled by some of its inbuilt means.
