Hi all,

If I install the moserial rpm from the repos, I can communicate with a serial device on /dev/ttyS0 just fine.

However, if I remove the rpm, and compile it from source, the program launches and connects to /dev/ttyS0 (as reported by lsof), but data transmission doesn't happen.

What could possibly explain the difference between the rpm version and the locally compiled version? Same code, but maybe different build flags? What would affect the serial port?

I can communicate with the remote device using minicom or tio (using their rpms).

selinux is disabled.
