HandNet for Windows
Unless you have a printer connected directly to the reader, you would typically
answer NO here. If you have a printer directly connected to this reader, answer
YES (most users working with HandNet print from HandNet rather than
connecting a printer directly to the reader). The only other time you might say
YES here was if you had a single reader connected directly to HandNet with a
serial port; there is a way to wire the connection to use RS-232 (if this were the
case, you would say YES, pick the appropriate baud rate, and then indicate that
RS-232 was connected to 1-Host (that is, HandNet)).
6. Once you are done, you see the Set Serial display again:
SET SERIAL
