*** SHAREWARE DOCUMENTATION *** The Personal Communications Library for Turbo Pascal (PCL4P) is an asynchronous communications library designed for experienced software developers programming in Turbo Pascal, version 4.0 and up. The PCL features: o 32 communications and support functions. o Support for the high performance INS16550 UART. o Supports hardware (RTS/CTS) flow control. o Interrupt driven receiver and transmitter (optional). o Supports 300 baud to 115,200 baud. o Supports the PC/4 and PC/8 DigiBoard. o Supports the BB1004, BB1008, and BB2016 BOCA boards. o COM1 through COM16 defined. o Adjustable receive queues from 8 bytes to 32 KB. o Control-BREAK error exit. o 18 communications error conditions trapped. o 4 ports can run concurrently (more with multiport boards). o Complete modem control & status. o Written in assembly language for small size & high speed. o Terminal program featuring ASCII (with XON/XOFF), XMODEM, YMODEM, and YMODEM-G. Several example programs ( source code ) are provided along with the small model library and makefiles for each of the supported compilers. The example programs are: (1) SIMPLE is an extremely simple terminal emulator program. It is provided as the smallest and easiest to understand example of communications programming using PCL4P. (2) TERM is a more capable terminal emulator than SIMPLE. It functions as a dumb terminal emulator but can exchange files using XMODEM (Standard XMODEM, XMODEM-CRC, and XMODEM-1K) and YMODEM (standard and YMODEM-G) communication protocols. TERM will also send an initialization string to your Hayes compatible modem. The shareware distribution does not include the source code to the library, but all example code is included. For more information, refer to the Personal Communications Library Users Manual ( PCL4P.USR ) and Personal Communications Library Reference Manual ( PCL4P.REF ), which are part of PCL4P41.ZIP. A C version of the library ( PCL4C ) is also available. *** Registration *** The shareware version of PCL4P.LIB is provided so that you may personally determine the usefulness of the product for yourself.
