I recently bought a external modem and Super Serial Card for my Apple IIe.
I'm basically using the computer as a terminal to access the class computers
on campus.  However, I'm having problems.  I have a DataLink Express modem
put out by Applied Engineering.  It can do 300, 1200, or 2400 baud.  It
only works okay on 300 baud.  At any higher speed, characters start to
drop.  I get no garbage characters though.  The missing characters seem to
happen in three character blocks.  Does anyone know what's causing this?
Does this sound like a modem problem or serial card problem?

	By the way, there is definitely no problem with the campus's
computers.  My friends get perfect input on their modems.  Also, I am
positive that I've set all the switches on the serial card correctly.
Also, the serial card that I bought was not new and was probably built
in the early 1980's.  However, it is a genuine Apple product.
