Uwe Hermann cb7b165b3d serial.c: Show both error code and error message.
This is helpful in many cases, e.g. when trying to identify which of the
16000 system error codes from

  http://msdn.microsoft.com/en-us/library/ms681381%28VS.85%29.aspx

has been encountered (which is not trivial if you only have an,
e.g. German, string message alone).

poljar (Damir Jelić) 1bd9e678ac serial: Add function to extract serial options.
This patch adds a function for a common operation of all serial based drivers.
It extracts the serial options from the options linked list that is passed down
to every hardware driver.

Martin Ling 9647ce694b Use new libserialport blocking/nonblocking API calls. 2013-12-01 18:51:24 +01:00
Uwe Hermann c4d85a4026 serial.c: Re-enable serial_read() error reporting.
libserialport now returns 0 (not SP_ERR_FAIL) as return value when a
non-blocking read would return EAGAIN.

This fixes bug #188.

poljar (Damir Jelić) 066d42b1c8 serial: Fix leak in serial_open.
A new sp_port is created every time we call serial_open (sp_get_port_by_name
implicitly creates one for us), so free it every time we call serial_close.

Daniel Thompson 5715e84fe3 serial: Only sleep when no characters are received.
g_usleep(XX) sleeps for *at least* XX microseconds but may sleep for
longers (on older kernels the sleep will typically be 10000us). Thus
byte receive loops containing an unconditional sleep will perform
very poorly (for example it causes the scan in agilent-dmm to timeout
prematurely).

Even on modern kernels serial_readline() has a 2ms sleep per byte which
means it will read at a maximum rate of half a character per millisecond
(~4800baud).

This is fixed by only sleeping when read() returns no data.

Uwe Hermann 045e9a9918 serial.c: Drop unneeded <glob.h>.
This is no longer used, and also it is not available on Android and thus
breaks cross-compilation for Android.

This is more correct anyway, and also a bit shorter and more readable.
