 Serial - Fossil driver interface for TP5  Marcos R. Della 29.06.1991

Интерфейсный модуль для работы с последовательным портом через Fossil драйвер. В качесте бонуса приведен модуль AnsiView.
SERIAL is a unit written to take advantage of many of the FOSSIL drivers out on the market such as X00.SYS or BNU.COM. If the system does not detect a FOSSIL driver in memory, then it resorts to standard interrupt driven serial I/O without the ability to open up more than one port at a time. ANSIView unit included.

SERIAL.PAS - 14 Jan 91 15 Jan 91 (Last Modification) By Marcos R. Della 5084 Rincon Ave. Santa Rosa, CA 95409 CIS: 71675,765 This unit is designed to allow the user to use a FOSSIL driver for a serial unit that is event-driven aware. To do this, the input from the modem is given an event status number just like the mouse or keyboard. All input is then routed directly through the event driver for all your dialogs to use. The output to the modem is in the form of a series of events that you can use or direct calls via an object. Note that these calls are the basics and do not halt for buffer overruns in either Tx or Rx. Your application program will have to monitor the serCarrier and serTxBuffer events to keep track if there is a carrier or if there is room in the TX buffer for more to be sent. Note that this unit was written to take advantage of many of the FOSSIL drivers out on the market such as X00.SYS or BNU.COM. If the system does not detect a FOSSIL driver in memory, then it resorts to standard interrupt driven serial I/O without the ability to open up more than one port at a time. (Currently... This may change in the future) ANSIVIEW.PAS - 24 January 1991 By Marcos R. Della 5084 Rincon Ave. Santa Rosa, CA 95409 CIS: 71675,765 This Unit was written so that I had something that reminded me of the original WRITELN and WRITE statments of pascal where I was working with the screen and there were various definate controls I had using the GOTOXY and CLRSCR routines. Under TVision, you no longer have these controls and need to learn a completely different way of getting info on the screen. AnsiView was written to give you some of these old methods while still using the TVision platform. That is, your screen is a scroll window of your size choosing (You can define a screen 128,2048 and use the gotoxy to get to anywhere on that screen!) Also if you turn on the ANSI option, the driver will recognise ANSI controls (For reading those ANSI files directly and displaying them!) Because this is also a TVision enviroment, your screen will also be saved if you do a desktop save! Wonderful stuff eh?
