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.   
 

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. 
 
 

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. 

 
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. 

 
 

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. 
 

NOTE: When installed, a 232PCC2 appears as a DSP-100 by 
Quatech, Inc.
