Description
Start or stop bit mismatch between computer and
Model 6517B.
Parity type mismatch between computer and Model
6517B.
Data received before previous data can be read.
A break occurred (device-clear occurs).
Noisy signal that could corrupt data.
RS-232 interface selection lost on power-up;
instrument defaults to GPIB.
RS-232 settings lost on power-up.
A character was received but discarded due to a lack
of input buffer space. Each line-feed character
(<LF>) closes a buffer and opens another. Thus, if
too many line-feeds are sent in succession, then all
buffers are filled before they have a chance to be
read.
A data format other than ASCII was selected.
