Hi,
I am currently setting up a console server using i386/1.4.1 on a Pentium =
133 PC. For my serial ports I am using 2 BB1008 8 ports Boca boards =
(dumb serial w/ 16550A) and both boards are sharing a single interrupt.
I am wondering how many such dumb ports using 16550A can share a single =
interrupt? My ports will all be configured at 9600bps.
Does anyone has some experience using high serial port counts?
Thanks.
Niloc.
