Is it possible to drive a 56K external modem @ 115200 using the serial
port on a DEC 3000/300? I remember a posting a while back saying the
interrupt handling code in the kernel had been re-jigged a bit, which
should vastly improve serial port throughput.
I'd be interested to know because currently my connection to the
Internet is via a flaky 9600 external modem connected to my DECstation
3100 running NetBSD/pmax 1.4.1 with ipnat enabled. I'd like to buy a
56K modem for my DEC 3000/300 running NetBSD/alpha 1.4-current, and
switch duties over to that, instead. (My ISP supports up to 56K.)
Speaking of buying an external modem for my DEC 3000/300, are there any
caveats? Looking on eBay, I notice a lot of external 56K modems are
being listed as "Windows" modems. Also, reading the fine print, I
notice some others use the Rockwell chipset. I'm guessing all these
require a certain amount of the modem functionality to be done on the
host computer, via a special driver? What are red flags to look for
when buying something that will work with my DEC 3000/300 under NetBSD?
