I purchased a Datalink Modem (2400 baud) about 2 months ago, and in general
I'm very happy with it. However, I'm running into occasional problems at
1200 baud. After running the Apple IIE enhanced for about 20-25 minutes at
1200 baud, characters start to get progressively garbled in both 
directions, and AT commands are sometimes converted to A% or A$ or A>, which
the modem doesn't accept. Even the output from a command like AT &V comes
out jumbled. Only turning off the machine for a couple of hours clears up
the problem. Oddly, the problem never occurs at 300 or 2400 baud. My 
machine currently has a CPM card, a mouse, 2 drives (5.25 inch), a fan and
a surge protector. Has anyone seen a similar bug? I tried to contact Applied
Engineering but their technical support line has been constantly busy.
