The 166550a was originally made by National Semiconductor. The C and CF models are okay too, according to this source. The A F version was a must-have to use modems with a data transmit rate of baud.
UART – Wikipedia
This generated high rates of interrupts as transfer speeds increased.
Dropouts occurred with Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a The corrected -A version was released in by National Semiconductor. The Art of Serial Communication. This page was last edited on 28 Novemberat The current version since by Texas Instruments which bought National Semiconductor is called the D.
From Wikipedia, the free encyclopedia. Technical and de facto standards for wired computer buses. Interfaces are listed by 16550w speed in the roughly ascending order, so the interface at the end of each section should be the fastest. More critically, with only a 1-byte buffer there is a genuine risk that a received byte will be overwritten if interrupt service delays occur.

National Semiconductor later released the A which corrected this issue. The A and newer is pin compatible with the Pages using web citations with no URL.
At speeds higher than baudowners discovered that the serial ports of the computers were not able to handle a continuous flow of data without losing characters. Exchange of the having only a one-byte received data buffer with aand occasionally patching or setting system software to be aware of the FIFO feature of the new catasheet, improved the reliability and stability of high-speed connections. Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers.
Retrieved from ” https: To overcome these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes.
