50g

8bit no parity is the default, at least it was on
previous models (hp48 & hp49). So, nothing to set but
the baud.

And you do need a serial cable but not just an
ordinary one. It's my understanding that the serial
port of the 50g doesn't meet the RS232 spec, voltage
is wrong as I recall. So you need a special cable made
just for the 50g. The one Matthew got at hpcalc.org
should be correct, I guess, since it works. I think it
was Samson Cables makes (or did make) one, too. See:
Message-ID:
<1172730293.195038.210160@...>

I have to qualify my statements by saying I don't have
a 50g and never used one in the serial mode, but have
use the 48g & 49g as such. I mostly lurk here but
occasionally reply when I'm pretty sure I'm correct.
