Why are you not using hardware flow control? Which platform and application

Hi Folks,
What is the most accurate wrist watch you can purchase? Obviously the
radio controlled ones are the best, but I'm curious as to the fully self
controlled units.
Oh and yes I have seen the photo of the caesium clock attached to
someone's wrist!

Interesting. I used to sell a GPIB-RS232 version some years ago. Sales were
low since customers were clamoring for an USB version! But then I hadn't
discovered this crowd :-) Happy to take another look at it.
I am in the process of designing a GPIB-Ethernet controller. You think that

hi jim, here's the thing you were asking for:
http://home.xnet.com/~cmaddox/omega_megaquartz_2400.html
as for myself - i do rely on a seiko 7548 reference quartz watch with
a 'drift' of +/- 15 sec. per month.
noz bad for a unit used for boiling eggs on a sunday morning ;-)
best regards,

GPIB-ENET controllers by NI are on and off available on eBay for about
$200. I would think there is a market for an ethernet/GPIB controller in
that price range.
I also second the RS-232 option. While the USB-parallel interface chip
has the potential of being much faster (which is great when
As someone pointed out, a Serial-USB adapter cost only about $10
(www.geeks.com), and I would not mind having a GPIB-Serial device, and
attach a Serial-USB if I want to. Once you provide USB only, that's it,
it will be USB or nothing. The one drawback of a Serial only controller
is that
I'll admit I'm kind of surprised at all of the users sticking up for RS-232.
I would've thought Abdul would be safe in abandoning his internal RS-232
data pathway between the Atmel and FTDI chip. What are some examples of
RS-232 hosts that need to talk to GPIB test equipment? Old/retired laptops
