Macintosh Plus P/C: No Response From Apple Personal Modem
PROBLEM DESCRIPTION: When using the old MacTerminal program
with the Macintosh Plus and the Apple Personal Modem, there is no
response from the modem.
CAUSE: The Data Terminal Ready (DTR) signal is not activated from
the old serial driver. This signal would normally be used by the
Macintosh to let the modem know that it is activated. Without DTR
the modem will not look at any other signals from the Macintosh.
CURE: Use MacTerminal 2.0 with the new system and finder because
it will activate the DTR signal on the Macintosh Plus.
If the above cure doesn't fix the problem, refer to the Tech
Procedures for this product's troubleshooting procedure.
