<DD>"This is a six printed page mini-FAQ with basic information on the PC parallel port. Many subjects are not covered in detail." This article describes direct hardware access, interrupt driven communication, bidirectional communications, File transfer, EPP, ECP, and even has sample code...<p>

<DD>This is a very complete document on the serial port. It contains lots of info about the hardware level implementation, connectors, interrupts, chipset interfacing (with the 16550/82450/16450/8250), chip detection, pinouts of serial driver chis, Mice, Modems, and even programming (C and x86 assembly).<p>Thanks to Acid/Gustavo for sending this my way!<p>

<DD>"Explains the pin diagrams of the RS-232 Port and the 8250 & Compatible UARTs. Includes information on handshaking, Null Modems, DTE/DCE Speeds, flow control, types of UART's etc. The second part of this series gives details of the Serial Ports Registers for the PC (8250 to 16750 UARTs) and the Serial Port's Addresses in the PC."<p>
<DT><font size=+1><a href='http://www.nondot.org/sabre/os/files/Communication/CP_Parallel.pdf'>Interfacing to the Standard Parallel Port</a></font> - by <a href='mailto:Craig.Peacock@senet.com.au'>Craig Peacock</a><br>
<DD>"Describes interfacing the Standard Parallel Port (SPP). Includes a general introduction to Parallel Ports (SPP, EPP & ECP)and their standards. Looks at reading 8 bits of data using the bi-directional port, and using other methods such as reading a nibble at a time etc. Also details the Parallel Ports interrupts. Programming examples using C are included along with a detailed description of the Parallel Port's Registers."<p>

<DD>"Interfacing the Enhanced Parallel Port is the first page, out of the Parallel Port Series which has been revised. This page,devoted entirely to the EPP port, now includes waveforms plus a more detailed description of this Port."<p>

<DD>"Interfacing the Extended Capabilities Parallel Port has just been revised. This page focuses on the Extended Capabilities Parallel Port (ECP), and now includes waveforms plus a more detailed description of this Port."<p>
