The B&B Electronics’ 3PXCC4A series serial interface cards are 

designed for the IBM PC, XT, AT and compatibles. Ports are 
configured as a standard DTE device, and connections are made on 
RJ45 style connectors. 

The 3PXCC4A cards offer exceptional setup flexibility. The 

3PXCC4A series has the ability to use any I/O address and any 
hardware interrupt. You can install as many serial ports as will 
physically fit in a machine. To use one of the “non-standard” 
addresses or interrupts, the serial software used must also offer that 
flexibility. If you are writing your own application, be sure the 
communications routines used support any address and IRQ. B&B 
Electronics’ SimpCom Communications Drivers support these 
features. 

Each port independently configurable for any hex address 0 to hex

Each port independently configurable for any interrupt: 2, 3, 4, 5, 6, 
7, 10, 11, 12, 14, and 15
