The A F version was a must-have to use modems with a data transmit rate of baud.

Dropouts occurred with The corrected -A version was released in by National Semiconductor. This page was last edited on 28 Novemberat Pages using web citations with no URL. National Semiconductor later released the A which corrected this issue.

This generated high rates of interrupts as transfer speeds increased. The Art of Serial Communication.

A Datasheet, PDF – Alldatasheet

To overcome these datasheey, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes. The current version since by Texas Instruments which bought National Semiconductor is called the D. Technical and de facto standards for wired computer buses.


From Wikipedia, the free encyclopedia.

The C and CF models are okay too, according to this source. Exchange of the having only a one-byte received data buffer with aand occasionally patching or datashert system software to be aware of the FIFO feature of the new chip, improved the reliability and stability of high-speed connections.

UART – Wikipedia

Interfaces are listed by their 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. The A and newer is pin compatible with the 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.

The also incorporates a transmit FIFO, though this feature is less critical as delays in interrupt service would only result in sub-optimal transmission speeds and not actual data loss.
