Well, a mere minicom instance at both side should be more than enough:
- person A types ATDT123456 to call person B
- modem of person B prints "RING"
- person B types ATA to answer.
- both modems print "CONNECT" once speed is negociated.
- whatever one types is printed for the other.

There's just one pitfall: both what person A and what person B type are
printed at the same location. One can disable local echo to avoid seeing
what one is typing, but that's typo-prone. It could be a nice additional
feature for minicom to have an option to split reception and emission
printing.

Alternatively, one can probably do the same by hand with a pair of cat
processes, but hanging up is more difficult than the minicom shortcut.
