This will set a timeout for read operations on the serial port. The intention is to prevent serio from hanging in certain situations. Signed-off-by: Tim Bird <[email protected]>
The data needs to be accumulated in this routine, when used with the 'count' option. Without this fix the routine only returns one byte of data (the last byte read). Signed-off-by: Tim Bird <[email protected]>
Don't use self.serial (even though it's available), but use self.fp, as that's consistent with the rest of the code.
The prevents data overruns when doing putfile on my setup, with io_time=0. This is faster (and likely more robust) than using io_time as a delay, but still prevents overruns on the target, when doing a putfile. Performance to put a 10000-byte file is: -P (io_time 0.1) => 41 seconds -t 0.05 (io_time 0.05) => 21 seconds waiting for prompt, but using io_time=0 => 7 seconds With io_time=0 and no wait for the prompt, serio hangs with the target stuck at the secondary shell prompt on my setup (beaglebone black, connected via Sony debug board). The target misses some of the data, and since it is in the middle of an echo of quoted material, the second quote is missed. Signed-off-by: Tim Bird <[email protected]>
This prints a time-stamped line for most of the interactions with the target. This is handy to see what gets sent to the target, and when it is sent. It's very verbose, and can only be turned on by changing the definition of "debug" in the source. To turn it on, change the line to "debug = 1". Signed-off-by: Tim Bird <[email protected]>

Hey Frank,
Here are a few bugfixes and new features for serio.
The most important of these is f57c90a to read the prompt after each transmitted line.
It works for me here, but I would appreciate it if you could give it a test on your system.
This significantly reduces hangs during putfile on my setup here.
Thanks,
-- Tim
