*** SHAREWARE DOCUMENTATION ***
The Personal Communications Library for Turbo and Borland Pascal
(PCL4P) is an asynchronous communications library designed for
experienced software developers programming in Turbo or Borland
Pascal. The PCL features:
o Supports protected mode.
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 COM20 defined.
o Adjustable receive queues from 8 bytes to 32 KB.
o Control-BREAK error exit.
o 19 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.
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) MINIMAL is the absolutely minimal terminal emulator program.
It is hard coded to use COM1 at 9600.
(2) SIMPLE is an extremely simple terminal emulator program.
Start it by supplying a port number and a baud rate,
SIMPLE 1 9600
(3) DOOR is very similiar to SIMPLE, but it "takes over" a port
in that the UART is not reset, and all parameters including
the baud rate are acquired unchanged.
(4) LOGIN is a variation on SIMPLE. It dials up the MarshallSoft
BBS and logs on as GUEST.
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.
