Panic in libcore

[crockpotveggies]

First let me say this is one of the most fun LoRa and Rust projects I've come across yet on the web :)

I'm running two LoStiks at close range with each other. One is on an Ubuntu Intel machine, the other on a raspberry pi. I'm using lorapipe over AX.25 and starting them using:

sudo socat /dev/pts/3,rawer EXEC:'./lorapipe-initfile=../../init-fast.txt --txslot 2000 --pack --debug --maxpacketsize 200 --txwait 150 --readqual /dev/ttyUSB0 kiss,pty,rawer'

Once I run both nodes and try an iperf speed test, my Ubuntu machine consistently crashes with:

thread '<unnamed>' panicked at 'Failure in readerthread: Custom { kind: Other, error: "Unexpected response: got -32, expected ok" }', src/libcore/result.rs:1165:5

Not sure what this is? The radio stops transmitting though and I have to restart the application.

Looks like this is coming from ser.rs, happens when --readqual flag is passed:

06:48:24 [TRACE] (2) lorapipe::ser: [src/ser.rs:65] "/dev/ttyUSB0" SERIN: -38

Please run with RUST_BACKTRACE=1 and --debug so we can see where the issue is occurring. It sounds like there may be an issue with the framing with the modem.

I highly doubt that iperf is going to be useful here, by the way.
