<b>ASYNC12</b>
Asyncronous Serial Communications Package for Turbo Pascal V5.0
Version 1.2 - 06/14/89
Copyright (C) 1989, Rising Edge Data Services
ASYNC12 is a full-featured Turbo Pascal UNIT that provides
interrupt-driven serial communication PC-compatable computers
utilizing standard serial port hardware (INS 8250's or equivalent).
Unlike similar offerings for Pascal programmers, ASYNC12 supports
full input and output buffering for up to 4 ports operating
CONCURRENTLY, with optional full hardware and/or software
handshaking. In addition, key high-demand subroutines as well as
the interrupt driver are implimented in assembly language for maximum
performance.
Baud rates to 115200 are supported, as well as non-standard rates
and all possible wordsize/parity/stopbit combinations allowed by
the 8250 UART.
Features -- Version 1.2
=======================
* Supports up to 4 ports simultaneously.
* Completely interrupt driven I/O for greatest efficiency.
* Assembly language used for interrupt driver and key high-performance
procedures and functions maximize throughput.
* Created as a Turbo Pascal UNIT for ease of use.
* Tight, well-commented, structured code for ease of modification/
enhancement.
Includes both Pascal and Assembly source.
* Supports both hardware (RTS/CTS) and software (XON/XOFF) handshaking,
at user's option.
* 28 procedures and functions in all to minimize programmer design time.
