PORT RS232
SPECIFICATIONS
Introduction.
This chapter details the specifications of the PCI 3Port
RS232 and PCI 3+1 Port RS232 serial card. The difference
between the two cards is simply the presence of a port header close
to the external ports. These half-sized cards will work happily in
any PCI 2.0 (or greater) compliant PC compatible.
