Subject: [PATCH] Replace awk with sed for WSL

The WSL distribution of Debian uses mawk instead of gawk by default, which
does not support matching into an array as it is currently being done for
extracting the COM port from the device name.

This commit replaces awk by sed, which also simplifies the building of
/dev/ttySx paths.
