Marcel Holtmann 4f3b99e189 Use 3 read attempts when in non-blocking mode 2010-01-28 22:24:04 +01:00
Marcel Holtmann c9a37e4a9a Add new constructor for fully blocking operation 2010-01-28 22:05:44 +01:00
Denis Kenzior fb918d39ba Fix: Take care of uninitialized variable condition 
In some (impossible) circumstances rbytes and err might be used
uninitialized.  Here we make a check that a read was actually attempted
before checking those variables.
 2010-01-28 14:38:59 -06:00
Marcel Holtmann 839988cfa3 Limit the number of continues read attempts 2010-01-28 12:41:31 +01:00
Denis Kenzior aebda1ac94 Refactor: Reorder argument order 
The order of arguments was a bit confusing, reorder them to make more
logical sense.

Zhenhua Zhang 7145edd3a4 Add gatutil.c to share common APIs with GAtServer 
Add gatutil.c/h gat.h and move shared typedef and APIs into it.
So that they can be shared by GAtServer and GAtChat.

Denis Kenzior e8d18946b9 Fix: One more fix for disconnect detection 
In situations where lots of data is generated by the remote side (e.g.
phonebook is being read) we can get our ring buffer filled up.  In this
case setting rbytes to zero first and then breaking out of the loop
leads to an erroneous disconnect detection.  The fix is to move setting
of rbytes after we know we still have some space.

Denis Kenzior cf98ebb653 Add: g_at_chat_cancel_all function 
This will cancel all commands currently queued.
 2009-12-02 19:10:04 -06:00
Denis Kenzior 9b5b1057e4 Fix: Sometimes it is possible to cancel first cmd 
Commands on the head of the queue can be canceled if none of its bytes
have actually been written to the modem.  This is tracked by
cmd_bytes_written variable.
 2009-12-02 15:27:26 -06:00
Denis Kenzior 0d022d3057 Fix: Don't allow cancelation of command id 0 2009-12-02 15:26:56 -06:00
Denis Kenzior 48a61b6d06 Fix: Retry the wakeup command until the modem OKs 
The calypso is weird where it doesn't actually wakeup on the first try,
we need to bang its head a few times until it responds

Denis Kenzior 112d07e14e Refactor: Add driver model to GAtMux 
GAtMux can now be made to work with multiple multiplexing protocols.
Currently on the 27.010 (07.10) Advanced and Basic modes are supported.
However, further protocol support can be added by providing the
necessary driver functions for GAtMux

Denis Kenzior 4734ebcb46 Refactor: Add convenience method to start 0710 MUX 
Use an existing GAtChat that has been setup appropriately to conver the
channel into a MUX
 2009-10-15 16:15:16 -05:00
Denis Kenzior 9aa2182261 Add ability to retrieve the atchat IOChannel 2009-10-15 16:15:16 -05:00
Denis Kenzior 556186eb35 Remove more unused code 2009-10-15 16:15:16 -05:00
Denis Kenzior 4c5cf38ddb Fix: Use DISC on dlc 0 instead of CLD 
Some MUX implementations do not seem to support Multiplexer Closedown
(CLD) command.  The standard specifies that sending DISC on DLC 0 should
act exactly the same as CLD.

Denis Kenzior e2415161de Fix: Make compile on some obscure platforms 2009-10-08 12:53:25 -05:00
Denis Kenzior f9db94cd73 Cleanup: Remove more dead code 2009-10-08 12:53:25 -05:00
Denis Kenzior efadf058c3 Cleanup: Get rid of unused member 
ctx->server is never set to anything but 0.  This was intended to handle
server side functionality of the GSM 07.10 multiplexer, but never fully
implemented.  Since GAtMux is only really meant for the client side, we
can safely remove this dead code.

Denis Kenzior 273c8b06a0 Get rid of from_tty variant, use gattty instead 2009-10-08 12:53:25 -05:00
Denis Kenzior 7e82686e70 Fix: Make next_hexstring handle optional quotes 
Ericsson MBM devices send CRSM information as hex strings, yet enclose
them in quotes which is not according to the standard.

Denis Kenzior 1a1f7d34d2 Add unquoted string capability

Denis Kenzior 789610389e Fix a problem with CtrlZ echo 
When a PDU is submitted and echoed by the modem, the CtrlZ character
is also echoed back.  Fix the parser to handle this case appropriately.

Denis Kenzior 88b327cff5 Cleanup the debug support patch 2009-08-06 16:38:46 -05:00
Andres Salomon d66fd48bf9 gatchat: add debugging infrastructure 
This patch adds debugging support to GAtChat (specifically of what's going
across the serial line).  Callbacks can be set via g_at_chat_set_debugging,
and that callback is called after any channel reads or writes.

Denis Kenzior d4536b3d2b Fix a crash with unsolicited notifications 
When a line comes in from the modem, we check against prefixes
in outstanding commands and unsolicited notifications.  If the
outstanding command has not yet been sent (cmd_bytes_written == 0),
we still check it resulting in access violation.

Denis Kenzior c74ea2093f Fix case where CMGS returns an error before pdu 
Commands like CMGS might return an error before the entire command
has been submitted.  This results in gatchat stalling completely.

Denis Kenzior c91ae28018 Fixes to parser state when command prompt is used 2009-06-19 21:14:00 -05:00
Denis Kenzior b648a112f2 Improve string parsing code 
Currently next_string and next_hexstring functions use a static
buffer in the iterator to store the value.  This value is clobbered
as soon as next_string or next_hexstring is called.  Instead,
we copy the entire line in iter_next and use it as a scratch buffer.
The only limitation is that lines of max 2048 are possible, however
these are limited to around this size by parts of the standard.
 2009-06-16 16:38:24 -05:00
Denis Kenzior 69372e642e Add g_at_send_listing function 2009-06-16 16:38:19 -05:00
Denis Kenzior 2222e1e38d Additional fixes to multiline responses 
The previous fix did not take into account the logic in have_line
function, which takes care of certain modems that do not prefix
their responses by <cr><lf> at all.  This fix should take both
into consideration
 2009-06-08 22:45:03 -05:00
Denis Kenzior fafdda30b9 Fix multiline responses in GAtChat 
The standard is a bit fuzzy on how multiline responses are returned
GAtChat assumed that they will always start with <cr><lf>, however
this doesn't seem to be correct.  Add a new state which is entered
when a response is obtained.  If <cr> is encountered, then it
is processed regularly, otherwise the parser assumes that the
next line is part of the multiline response
