- 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 28 communications and support functions.
- o Support for the high performance INS16550 UART.
- o Supports hardware (RTS/CTS) flow control.
- o Interrupt driven receiver.
- o Supports 300 baud to 115,200 baud.
- o Supports COM1, COM2, COM3, and COM4.
- o Adjustable receive queues from 8 bytes to 32 KB.
- o Control-BREAK error exit.
- o 17 communications error conditions trapped.
- o Allows 2 ports to run concurrently.
- o Complete modem control & status.
- o Written in assembly language for small size & high speed.
- o Terminal program featuring XMODEM, YMODEM, & YMODEM-G.
-
- Why should you buy PCL4P ? I can give you several good reasons.
-
- COMPLETE - PCL4P is complete since it provides absolute control
- of the serial ports (including the high performance
- INS16550).
-
- COMPACT - PCL4P is very compact at less than 6 KB. Your
- application doesn't carry a lot of excess code.
-
- FAST - PCL4P is fast since it will run at 38400 baud on
- even slow 8088 PCs (4.77 MHZ) and at 115200 baud on
- most everything else.
-
- SUPPORT - If you get stuck, you talk to the programmer that
- wrote the code, not a person hired to answer the
- phone.
-
- BBS - A BBS is available (2400 baud N81) in order to
- provide immediate support as necessary.
-
- NEWSLETTER - One year subscription to the MSC newsletter
- discusses communications problems and solutions
- (published quarterly).
-
- PRICE - You get PCL4P for a very reasonable price !
-
- UPGRADES - Once you buy PCL4P, you can always update to the most
- recent version for little more than the cost of
- sending it out to you.
-
- 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 PCL4P32.ZIP.
-
- A C version of the library ( PCL4C ) is also available.
