tools: atrf-id option -s to retrieve driver spec, with necessary infrastructure
- include/atrf.h (atrf_driver_spec), lib/atrf.c (atrf_driver_spec):
new function to retrieve the local or remote/final driver spec
- lib/atrf.c (struct atrf_dsc, atrf_open, atrf_close): record the local
driver spec
- lib/driver.h (struct atrf_driver): new driver function "driver_spec"
to retrieve the driver spec
- lib/atnet.c (struct atnet_dsc, atnet_open, atnet_close): maintain a
cache for the driver spec
- lib/atnet.c (atnet_driver_spec, atnet_driver): added support for the
"driver_spec" function
- atrf-proxy/PROTOCOL, atrf-proxy/atrf-proxy.c (cmd_zero): added command
SPEC to retrieve the (final) driver spec
- atrf-id/atrf-id.c (usage, main): added option -s to retrieve the
driver spec. One -s retrieves the local spec, -s -s the remote/final.

Message format
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
Commands are not case-sensitive. Messages and comments consist of printable
|
|
|
|
|
ASCII characters and spaces.
|
|
|
|
|
|
|
|
|
|
Whitespace separating words is always exactly one space character.
|
|
|
|
|
Lines end with a * single newline, without trailing whitespace.
|
|
|
|
|
Numeric values are in C notation, i.e., 64, 0100, and 0x40 would all
|
|
|
|
|
represent the same value.
|
|
|
|
|
|
|
|
|
|
"raw-data" is a string of binary data of the indicated length. The other
|
|
|
|
|
formatting conventions remain valid after this string, i.e., it must be
|
|
|
|
|
followed by a single newline.
|
|
|
|
|
|
|
|
|
|
The device is implicitly opened when establishing a TCP session. The
|
|
|
|
|
device is implicitly closed when closing the TCP session.

Asynchrous interrupt notification (not implemented yet)
|
|
|
|
|
---------------------------------
|
|
|
|
|
|
|
|
|
|
The WAIT command is not answered until an interrupt or another command is
|
|
|
|
|
received. WAIT returns the interrupt status, just like POLL.
