[comp.sys.mac.hypercard] DIAL dropping dtr ???

tenney@well.UUCP (06/03/88)

I should hope this is old hat:  Running on an SE now, I find that
I can't DIAL any numbers.  HC starts dialing the number and then
just drops DTR which hangs up the phone (before finishing dialing.)

Huh?  What gives?  More importantly, how can I fix it?
