Command Groups; Control-Key Commands - Data I/O 298 Manual

3. The 298 message displayed on the terminal when first
entering TRC has one extra line-feed preceding the
text. Otherwise these messages are the same.
4. For the Model 298 after the end of an input or input
compare data translation there must be a pause of
incoming characters for 1 /2 second before the prompt
is returned. All incoming characters after the end of
data translation and before the returning prompt are
purged (thrown away).
5. The System 19 sends out an extra carriage return,
linefeed, and null count after the STX (start character)
for formats 01 through 09, 12, 13 whereas the model
298 does not.
6. The Model 29B sends out an extra carriage return,
linefeed, and null count after the leader for formats 10
and 11 whereas the System 19 does not.
7. During input or input compare translation the System
19 beeps each time an error occurs whereas the Model
298 does not.
8. For the Model 29B a BREAK or ESCAPE key
depressed during input or input compare translation
will abort the operation just as with System 19,
however, the Model 29B will not return a prompt until
data stops coming in.
9. The "SM" (Memory Size) command with the Model
29B will show only the lower 16 bits of a 17-bit ending
address if the "VM" (Virtual Memory Offset) command
has been defined to be greater than zero. If the
address offset is equal to zero (its default value) then
there is no problem since the ending address can be
shown with 16 bits.
10. Generally the quantity of errors given in response to
"QB" (Input Compare Errors), "QC" (Buffer-Overflow
Errors), and "OD" (Error Status) commands will be the
same for both the System 19 and the Model 29B,
however for some translators the quantity may be
different.
B.3 COMMAND GROUPS
The commands available in remote control are grouped
according to their functions. Tables B-1 through B-6
summarize the commands available in remote-control
operation of the programmer, as well as programmer
responses to these commands. Syntax for the commands
in the summary tables is shown in section 8.4.
Control-Key Commands
The Control-Key Commands summarized in table B-1 are
used to execute or suspend a command, or to display the
last command.

DESCRIPTION
Abort a command. The BREAK key is used to abort a binary
data transfer. Note: When using during the execution of the
"DI" or "DC" command may not abort the command if a data
stream continues to come into the programmer from the remote
terminal or computer.
Re-executes the D, I and C commands. Note: With the 'C' and
'I' command the data parameter must be entered each time.
Displays the last command executed. Note: Does not function
for memory mode commands.
Executes a command or re-executes a previous command. The
letters [CR] are used in this appendix to represent the return, or
carriage return command. Note: Does not function for memory
mode commands.
