Yes, they are. I have swapped the 16450 to 16550 on many of my PCs. Be aware though that the 16550 will work exactly as a 16450 unless software enables use of the fifo. QMODEM, and some other [PC BASED] terminal programs will support the 16550. If the program you are using fails to explicitly enable the FIFO, it will have no effect.
