C to the Porta-Weigh Plus
The Porta-Weigh Plus does not have an EIA-232 input buffer. This
limits how fast commands can be sent. Some delay (~10ms) between
ASCII commands should be included in any software written to
control the Porta-Weigh Plus. The speed of data transmission is
limited only by the baud rate and the user interface. The response to a
print command is virtually instantaneous. However, transmission of
new, updated, data from the Porta-Weigh Plus is limited by the speed
of the A/D conversion, and the filter setting. The low filter limits the
data update to a 2 per second rate, the medium is about 1 per second,
and the high setting has about a 1 per 2 second update rate. These
