Chapter 2 Command Descriptions 171
If the device you are configuring does not fit into the device types listed
in the previous table, or requires unusual flow control attributes, use the
information in the following table to define a device type.
Note that for “mio,” “mout,” “min,” “host,” and “hdial” device types, the
device lowers DTR at disconnect and holds it low for two seconds to
ensure a clean disconnection.
Device Type Use for Devices with These Attributes
hdial • The device generates a login when carrier is detected (DCD high) and data is received.
• The device closes the port at carrier loss (DCD low).
• DTR and RTS are low when the connection is idle.
• This type does not support reverse Telnet or RealPort.
• This type requires 10-pin cables with DCD and DTR cross-connected or an altpin cable.
hio • The device generates a login when carrier is detected (DCD high) and data is received.
• The device closes the port at carrier loss (DCD low).
• DTR and RTS are low when the connection is idle.
• This type requires 10-pin cables with DCD and DTR cross-connected or an altpin cable.
host • The device does not generate a login.
• The device opens the port at DCD high and closes the port at carrier loss (DCD low).
• DTR and RTS are low when the connection is idle.
• This type supports reverse Telnet and RealPort.
• This type requires a cable that supports carrier detect (DCD).
ia • The device never generates a login.
• This type usually requires cable support for transmit, receive, and ground only, which
means a 3-wire crossover cable will work. Six, eight, and ten wire crossover cables work
as well.
• Specifying “dev=ia” enables port support for industrial automation. See "set ia" on page
125.
min • The device server generates a login when carrier is detected (DCD high).
• The device server closes the port at carrier loss (DCD low).
• DTR and RTS are high when the connection is idle.
• This type requires a 10-pin straight-through cable or an altpin cable.
• Do not use "dev=min" for RealPort and reverse Telnet connections.
mio • The device generates a login when carrier is detected (DCD high).
• The device closes the port at carrier loss (DCD low).
• DTR and RTS are high when the connection is idle.
• This type requires a 10-pin straight-through cable or an altpin cable.
mout • The device never generates a login.
• The device closes the port at carrier loss (DCD low).
• DTR and RTS are low when the connection is idle.
• This type requires a 10-pin straight-through cable or an altpin cable.
• dev=mout supports RealPort and reverse Telnet.
