ADFM Commands
>RS
RS = 002,022 ---- REC SPACE USED (MB), FREE (MB), (999 = ERASING)
This shows the ADFM contains a 24-MB recorder (2 + 22).
Up to 2 MB of space is used with 22 MB of free space. If at
least one byte is written to recorder memory, RS will show
that a full megabyte is used. While the recorder is erasing, RS
= 999,999.
RT - Recorder Bit
Purpose: Tests the recorder using either non-destructive or destructive
methods.
Format: RT
Description: RT tests recorder RAM, detects the number of memory cards,
checks card communication, and checks recorder functions us-
ing either non-destructive or destructive methods.
This command is not implemented in Intel recorders.
Example 1: Non-destructive test - This test checks recorder operation
without destroying previously recorded data. Write operations
are done on "free" areas of the recorder. This test writes to
and verifies low and high recorder RAM, detects the number
of recorder cards installed, determines the total recorder mem-
ory capacity, tests write/read/block copy operations. This test
takes less than 30 seconds to run. The format and output dis-
play are as follows.
Example 2: Destructive test - This test fills all recorder memory space
with a pattern, and then verifies the pattern. During the test,
the number of sectors tested is also displayed. This test must
immediately follow the RE ErAsE command. This test takes
about one minute per megabyte of recorder memory to run.
The format and output display are as follows.
>RE ErAsE <- Must immediately precede the rt-command for destruc-
tive testing
[Erasing...]
>RT
0 2 14 0 0 0 0 <-- Output format is same as non-destructive
test
Sectors Checked 40960 <--- 2096 x Number of recorder memory mega-
bytes
Sending a <BREAK> aborts this test.
