- drops DTR, delays and the raises DTR before retrying modem commands
Improved log output:
- don't log COM Device value when passed live com handle/descriptor on cmdline
- log COM Device value in modem command/response errors
- more debug-related log output
Fix modem re-initialization time-out (off by one)
- ReInit value of 1 would result in reinit every 2 minutes of inactivity
