Warning about the AT&T 300/1200 baud ACU/modem made by Penril: it is prone to
overheating, partly because it comes in a heavy metal box without airholes.
We kept four stacked on top of each other for a while and they became flaky;
one had obvious burn damage inside.  We removed the front covers and turned
them to stand on their sides, and they have worked perfectly ever since.
The AT&T Autocall 2224 (300/1200/2400 baud) modem doesn't seem to get as warm.
