I used to have a 386SX/16 here in the office with a SMC Ethernet card and ^^ a bunch of 16550's, that I used as a terminal server (recently upgraded to a 386DX/16). It handles 4 modems, a high speed (38400) network connection to another box, and from time to time when I am loading FreeBSD, I connect another 386sx/16 with 16450's, and set up a hardwire SLIP link between the two at 115200. I typically see about 5000cps on the SLIP link between the two, and am fairly certain it's the machine with 16450's that's limiting the throughput. So I know of at least one 386sx/16 that can soak up 38.4k with 16*4*50's, and my router was certainly capable of blasting lots of data all over the place at speeds rather higher than that.... ...
