6 PCL-849 User's Manual Description The PCL-849 series are four port serial communication interface cards. Each port can be configured individually to RS-232 using on- board jumpers. PCL-849A/849B serial ports are implemented using 16C554 UARTs which make serial I/O more reliable. For higher performance, 16C654 UARTs can be installed in place [...]
