This question gets asked periodically, so I figure I'll just post the latest info on how to get the X.PC source and documentation. X.PC INFORMATION AND UPDATE POLICY Revised August 1, 1988 X.PC IS A PUBLIC DOMAIN PROTOCOL. THERE IS NO CHARGE FOR THE X.PC DRIVER FOR THE PC OR ITS CONCEPTS. However, for a small cost-defraying charge, the X.PC technical documentation with source code on diskette is mailed out on the second Monday of each month. It is sent by first class mail through the U.S. Postal Service. X.PC Packet Information The X.PC Packet provides guidelines to interface the X.PC Driver to an application on an IBM PC (and 100% compatible) that runs under MS-DOS or PC-DOS, version 2.00 and above. Two sample applications (with source code) are provided on diskettes with the X.PC Driver Module. Also provided are development utilities which monitor the interaction between your application and the X.PC Driver Module. If you wish to modify the driver or to port the X.PC Driver to other hardware or operating environments, the source code for the X.PC Driver Module is also provided. The code is mainly written in Microsoft C, and IBM Macro-assembler to manipulate the 8250 communications processor. Also included with the X.PC technical documentation and state diagrams is a utility that allows a PC with two serial cards to be used as an X.PC line monitor/protocol analyzer. X.PC Packet Cost A check for $35.00 ($45.00 if outside the United States) covers the cost of five (5) diskettes, the documentation, and the postage and handling. X.PC Packet Rush deliveries Rush deliveries are processed only if the check and the completed request are accompanied by a self-addressed (with billing account number) airbill for overnight delivery. Self-addressed airbills for Federal Express, DHL, or Airborne are accepted. No "bill recipient" or COD (such as UPS) will be processed for rush delivery. How to Order the X.PC Packet 1. Complete the X.PC Information Request order form on page 3. 2. Attach a check or money order payable to "BT Tymnet" for $35.00 ($45.00 if outside the United States), to defray the costs of the diskettes, shipping, and handling.
