Does anyone know anything about whether SCO Unix can take advantage of high speed serial UARTs (NS16550AFN, etc) and hardware flow control? I've heard FAS drivers mentioned for Interactive - can someone expound on this. Thank you muchly -- \\\ - - Richard Ducoty ..uunet!grumbly!root _] Capitola, California root@grumbly.com

First question: No, the standard SCO serial drivers do not take advantage of the FIFO buffer in the NS16550AFN UART. Second question: I took a brief stab at getting the FAS driver working under SCO UNIX 3.2.1. I had no success. I hasten to add I am not an expert at these matters. If anyone was able to get this driver working under SCO's Unix, I would love to hear about it. -- Dr. Victor L. Rice Litwin Process Automation

Actually SCO UNIX System V/386 release 3.2 version 2 which is now shipping *does* take advantage of 16550 FIFOs - this was one of the features added in SCO 3.2.2
