vary wildly in how faithfully they emulate a real serial port.
Especially how they emulate (or don't emulate!) the hand-shaking lines
of a real serial port since these lines don't exist in USB. Some will
work only with some programs, others with nearly all. The Belkin
converters are especially notorious for poor compatibility and have
been repeatedly blasted on this list, the UIview mailing list and the
MixW list. <br>
<br>
Some of the variables involved are: <br>
o What IC chipset is the cable based on? <span class="281473102-04092005"><font color="#0000ff" face="Arial" size="2">[Doug

YES !!! These cables are active devices with dedicated
microcontrollers encapulated in the DB9 housing. <br>

Just to emphasize that the "Yes it works, No it doesn't" reports from
other users don't prove anything unless you indicate what OS you are

As I pointed out in my original post, that fact that the thing works
with app A (Hyperterm) won't prove it will work with app B (APRSpoint).
This is due to differences in various applicatons' tolerance for
less-than-perfect emulation of hardware I/O buffer stacks, interrupt
latencies, hand-shaking timing,etc. <br>
