Serial port is unresponsive

[tresf]

Using Ubuntu 16.04 but also tested against 14.04 in VM and physical workstation.

From @klabarge's wiki:

sudo apt-get install libdevil-dev libtool-bin libtool libfontconfig1-dev clang libelf-dev freeglut3 freeglut3-dev gcc-avr avr-libc gcc make git libcairo2-dev picocom
git clone https://github.com/buserror/simreprap
cd simreprap
make -I shared/libc3/
SIMAVR_UART_XTERM=1 obj-x86_64-linux-gnu/reprap.elf

What happens:

• ✅ Simreprap opens and is responsive
• ✅ xterm -e picocom -b 115200 launches with what appears to be a serial session to Marlin
• ⛔️ Serial port is unresponsive to any commands or GCODE

We also tried:

• ⛔️ echo-ing to the /dev and to the /tmp/simavr-uartXXX with no response
• ⛔️ putty-ing to the /dev and to the /tmp/simavr-uartXXX with no response

Is there a step we're missing or is simreprap incompatible with Ubuntu?

Any updates on this? I ran into the same issue:

"avr_sadly_crashed" doesn't sound too well either :)
