Chapter 1: Introduction
B&B Electronics 232PCC2 provides two independent RS-232
asynchronous serial communications interfaces for systems
equipped with PCMCIA Type II and/or Type III expansion sockets.
The 232PCC2 is a PCMCIA Type II (5 mm) card and is PCMCIA PC
Card Standard Specification 2.1 compliant.
equipped with PCMCIA Type II and/or Type III expansion sockets.
The 232PCC2 is a PCMCIA Type II (5 mm) card and is PCMCIA PC
Card Standard Specification 2.1 compliant.
The 232PCC2's serial ports are implemented using 16C550
Universal Asynchronous Receiver/Transmitters (UARTs) that are the
recommended communications interface for multitasking
environments and applications involving high data transfer rates.
recommended communications interface for multitasking
environments and applications involving high data transfer rates.
The 232PCC2’s two serial ports are addressable in two modes:
1. Block Mode: The two serial ports are configured in one 16-byte
continuous block of I/O address space. The block must begin
on an even 16-byte division. Both serial ports share one IRQ
level.
on an even 16-byte division. Both serial ports share one IRQ
level.
2. COM Mode: The two serial ports are configured at the standard
COM port I/O address location. The ports may be configured as
COM1 and COM3; also, the ports may be configured as COM2
and COM4. Both serial ports share one IRQ level.

and COM4. Both serial ports share one IRQ level.
A special interrupt status register is also available to simplify the
software required to service multiple serial ports in an interrupt
driven environment. See the Hardware Information section for
details.
