[comp.sys.apple2] External Modem Problem

Fletch <DWRYMANO@MTUS5.BITNET> (06/14/91)

I recently purchased a Zoom 2400 External Modem.  I'm trying to use it with a
Super Serial Card.  I have the jumper set to MODEM and have all the DIP
switches set to what's in the manual.  It will dial and connect, but NOTHING
comes back to the screen.  The RD and SD lights both blink when I type.  I've
tried changing the echo and that doesn't help either.  Does anyone have any
idea what might be wrong?
Please email any suggestions to:  DWRYMANO@MTUS5.CTS.MTU.EDU

Thanks much!
