RS232.C was written to provide all of the basic functionality needed
to employ serial I/O in any application written with Borland C
language compilers. Some features are:
1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided.
2. Both input and output are buffered and interrupt driven for efficiency.
3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available.
4. Detection and utilization of hardware buffered UARTs (NS16550AF
etc.) found in some machines is automatic.
5. Interrupt driven hardware and XON/XOFF flow control is provided for.
6. All source code is included. RS232.C can be used with all memory
models.
