The Ultra COMM+8.PCIe provides eight RS-232/422/485 ports from a single PCIe slot.
The Ultra COMM+8.PCIe utilizes the 16C950 UART. This chip features programmable baud
rates, data format, interrupt control and industry leading 128-byte transmit and receive FIFOs.
The UARTs are register compatible with 16C450, 16C550, 16C654 and 16C750 UARTs. The
FIFO depth can be changed to match the depth of these UARTs.
