DOS Serial Communication Library

The Personal Communications Library (PCL) series of products consists of real mode and 16-bit DPMI protected mode LIB's containing functions providing control of the computer's RS232 serial ports.

The PCL libraries are designed to be run from DOS (not a Windows DOS box) and directly access the computer's serial port hardware. Each product comes with example programs and complete documentation.
