WHAT TO DO
•
Change to a lower baud rate.
Make sure that the new 1256
baud rate matches the new
terminal baud rate (to set the
1256 baud rate, see Chapter
4, GPIB and RS-232
Interfaces, under the heading
Setting the Baud Rate).
•
Use a high-quality, shielded
cable.
•
Set 1256 to use carriage return
and line feed (CR-LF) as
termination characters (see
Chapter 4, GPIB and RS-232
Interfaces, under the heading
Setting the Message
Termination Characters).
•
Set 1256 to use only carriage
return (CR) as termination
character (see Chapter 4,
GPIB and RS-232 Interfaces,
under the heading Setting the
Message Termination
Characters).
•
Set terminal for half-duplex
(local echo) mode. Consult the
terminal user's manual for
instructions.
