Is TeraTerm-5 a good candidate?

It should be fine, especially if you have no particular fancy requirements (say, like display hex decoding, or timing info.)
I use minicom on unix/MacOS and putty on windows, but I also don't do enough with them to have found their limits. (The minicom UI is a bit ... dated.)
If I use my Arduino Micro for this, will the Rx and Tx be addressed with the "serial"-commands?
And will the IDE still be available for other communications.
On a 32u4 board like the Arduino Micro (which has "native USB"), Rx and Tx will usually be "Serial1", and "Serial" will be available for communications back to your PC.
(I've seen an occasional "board" definition, I think from Sparkfun, where "Serial" was Rx/Tx and "SerialUSB" was the PC connection, but it's less common.)
