HRM
<checksum2(2»:
is the checksum for the data por-
tion of the record (two ASCII char-
acters)
<carriage return>: indicates the end of the record
No segment information is transferred. All downloaded
data is loaded into segment 0 with the LOAD command.
Data for segments other than 0 must be transferred to
Segment 0 by the MOVE command.
LAST RECORD
<entry address(4» 00 <checksum(4» <carriage return>
where:
<entry address>: is the starting execution
address for the program
<checksum>: is the checksum for the
entry address
NOTE
A record ~ith 00 in the count field indicates the
en~ of load data.
RECORD WITH ERROR MESSAGE
If either the local or remote system has to abort the load
process, it sends a record of the form:
/ <error messages in ASCII text> <carriage return>
ACKNOWLEDGE
During the loading process, after each record is re-
ceived from the remote system, an acknowledge (ASCII 0)
is sent when the checksum values are verified. If a
nonacknowledge (ASCII 7) is received, the remote system
attempts to load the same data record up to ten times.
After the tenth try, the Monitor Program returns to Mon-
itor Mode for the next command. An abort-acknowledge
(ASCII 9) is sent to the remote system if the escape
(ESC) key is pressed, aborting the loading process. The
