@Famicoman Do you have any sort of pbx? My Panasonic 824 makes playing with modems fun. Other models that work good for this type of stuff are the 308 and 616. The 308 real popular with telephone collectors.
The thing about these Gandalf modems however is that they are meant to be used without any reliance on a PBX or telephone network. Ideally you'd use them in a college campus to connect terminals to machines over a great distance by doing point-to-point wiring over existing telephone wire drops.
