ZLOADER
Starts the s–record load utility.

LOADER
Description
The command starts a loader utility program that downloads files in
Motorola s-recordformat (S3/S7 type) into memory from a device connectedto the
system console serial port. The SCM recognizes s-records only after you use the
command.
An s-recordis a file that contains an unlimitednumber of records; each recordhas a
maximum of 256 bytes. A server machine uses s-records to download an entire file
serially. The loader utility copies s-records from the serial port into system memory
on the local (client) system. The SCM reads information appended to individual
s-records, stores each recordat locations specifiedin the s-recordheader, andthen
verifies checksums. Information appendedto the last s-recordnotifies the SCM when
the entire file has been sent.
For this commandto function, you must configure your system to use an s-record
utility anda server machine must be sending s-recordfiles. If you are not familiar
with your system's s-recordloader utility, if your system is not configuredto receive
s-records, or if the server is not sending, press the Ctrl-C sequence to exit from the
command.
NOTE: Your system will pause indefinitely until it receives the last s-record in a file,
or until you execute a Ctrl-C commandsequence to exit to the SCM prompt.
