Alexandru Gagniuc 3ebc9b59a2 metex14: Fix parsing of measurement flags.
strcmp(buf + 9, "  mA") does not work because buf is CR-terminated,
while "  mA" is NUL-terminated.

Drop ambiguities arising from the termination of the strings, and
only compare the characters we care about, using strncmp().

The packet is an ASCII string. We can simply print the raw packet data.

Alexandru Gagniuc 76b55dfa8a metex14: Fix parsing of spaces.
When the parser found a space, it treated it as an invalid digit
and discarded the whole packet. This behavior was incorrect on
2000 count devices, where the first digit can be sent as a space
rather than a '0'.

Convert spaces to '0' and parse them as usual.

Uwe Hermann 21a7f2692e Rename tekpower-dmm to serial-dmm.
This is now a generic driver for multiple DMM "subdrivers" that use simple
serial port protocols.

Uwe Hermann 729b01f988 tekpower-dmm: Generalize & first-class TP4000ZC driver.
Prepare the tekpower-dmm driver to be able to support various simple
serial port based DMMs.

Also, make a 'tekpower-tp4000zc' "first-class" driver which is currently
the only user of this generic driver.

Alexandru Gagniuc c216d62307 demo: Properly stop acquisition after reaching our sample quota
The demo driver was using sr_session_source_add_channel() to add
a poll source, but was relying on sr_session_run_poll() to call
sr_session_source_remove(). This, coupled with the design of the
driver caused errors once the samples were collected.

The error stream was most likely related to failing to properly close
one of the channels.

This is the first step in fixing the demo driver: figuring out what is
being called and what is not _and_ have it show up in the logs.

Bert Vermeulen 71caaad46b serial: allow for extra rts and dtr options in conn string
Options in addition to the usual "9600/8n1" syntax start with a
slash, and take the form of key=value, where different options are
also separated by slashes. For example:

	"9600/8n1/rts=0/dtr=1"

This sets RTS low and DTR high.

Alexandru Gagniuc 2ecc5d432f radioshack-dmm: Check for valid mode before calculating checksum
The packet mode byte is akin to a signature. If that is invalid, there's
no point in calculating the checksum, so check the mode first.

Alexandru Gagniuc 2546b05c80 tekpower-dmm: Improve serial detection.
Serial detection was using serial_readline, which stripped carriage
return from the packets. This made for a very unreliable detection
mechanism.

Switch to a timeout-based detection mechanism that parses the data
as it comes in. This also allows us to stop parsing once we found
our first valid packet.
