8 Configuring PAD/ATPAD Ports
PAD Port Configuration
DIMO A crossover cable attaches a dial modem to the port,
and whose handshake uses modem control signals as
calls are made. Types of DIMO operation are:
• Dial In: Calls received from the telephone
network.
• Dial Out: Calls received from the port.
• Dial In/Dial Out Collision: Calls received
simultaneously from the telephone network and
the port.
DIMOa Same as DIMO but DSR is never raised on incoming
call.
DIMOb Same as DIMO but DSR follows DTR on incoming
calls.
EMRI A port connects to a host computer and replaces a
modem. The port emulates a dial modem with Ring
Indicator (RI).
EMDC A port connects to a host computer and replaces a
modem. The port emulates a dial modem with Data
Carrier Detect (DCD) used to signal an incoming
call.
EMCDIO A port connects to an asynchronous host computer
and emulates a modem with DCD for incoming and
outgoing calls.

Range: NONE, MB
Default: NONE
Description: MB enables the make-busy feature for the specified port; disabling
the port raises pin 22 only when Connection Type = DIMO,
DIMOa, DIMOb, DTR, DTRD, or SIMP.
Note
NONE (disables the Make Busy feature)
