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 tele phone

 

 

 

 

 

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.

 

 

 

 

 

 

 

Port Control

 

 

 

 

 

 

 

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)
