/*
Design remarks.
This entry must accept up and downloads at the same time in case a users
wants to download but uses a bidirectional protocol and has something to
upload.
First design fase: support the now used external protocols and link it to
the rest of the bbs.
Second design fase: add build-in zmodem and ymodem-1k.
To think of:
- Drop bidirectional support, is this still in use. No bimodem specs and
Hydra seems not implemented in any terminal emulator.
- Add sliding kermit? Can still be used externally.
- Add special internet protocol and make a module for minicom. No, this
would mean only a few users will use it.
