11801C User Manual
H Stop Bits lets you select among 1, 1.5, or 2 stop bits. Touch the
selector repeatedly until the appropriate number is shown in the selec
tor. You should set the number of stop bits to match the computer you
are using.
H Parity lets you select among Even parity, Odd parity, or None. Touch
the selector repeatedly until the appropriate setting is displayed in the
selector. Parity is an error detection scheme. You should set parity to
match that of the computer you are using.
H Flagging lets you select among Hard flagging, Soft flagging, or
None. Touch the selector repeatedly until the appropriate setting is
displayed in the selector. Flagging is used by the 11801C or the comput
er to signal that its input buffer is full, and that the other device should
stop transmitting until further notice.
When soft flagging is selected, the 11801C sends a Ctrl S (decimal 13)
to signal the other device to stop transmission, and recognizes Ctrl S as
a signal to stop transmitting. Ctrl Q restarts transmission. When hard
flagging is selected, the 11801C uses the RS 232 C DSR/DTR signal to
control data transmission. You should set the type of flagging to match
the computer you are using.
H Delay assigns the knobs to baud rate and delay. Delay is the mini
mum time that the 11801C will wait before responding to a command
sent from the computer. The delay setting can be 0 to 60 seconds.
H EOL String lets you select the end of line query terminator to one of
the following: LF (Line Feed), CR (Carriage Return), CR/LF, or LF/CR.
Touch the selector repeatedly until the appropriate setting is displayed in
the selector.
H Verbose lets you set verbose ON or OFF. When verbose is on, the
11801C posts to the computer a message indicating the success or
failure of each command sent to the 11801C. When verbose is off, the
computer can specifically query the 11801C about the success or failure
of each command if so programmed.
H RS232C Debug
the 11801C displays each command from the computer as it is
executed. The messages appear at the top of the display. Debug off is
the normal mode of operation. Set debug on if you need to watch the
result of each 11801C command of a program that is running in the
computer. When debug mode is on it slows performance significantly.
lets you set debug ON or OFF. When debug is on,
