Porter Models
The Porter is available in a 4 / 8 serial port or 4 / 8 port
parallel port version.
Installation
The Porter uses commonly available cables and works with
any device with serial or parallel ports. The Porter's serial ports are DB25
and its parallel ports are Centronics.
and its parallel ports are Centronics.
Basic Concepts
Porter accepts data from a computer or terminal and
sends the data to a selected port. The port is selected by sending a code to
the switch. The code or command is not sent to the destination port. Porter
also accepts other commands to control the flow of data. The commands
consist of an attention code (prefix) and command characters.

Buffer Memory
The buffer is divided into a receive and transmit buffer
for each port. The amount of buffer available for each port is the total buffer
divided by the number of ports. For example, a unit with 8 ports and a 256K
divided by the number of ports. For example, a unit with 8 ports and a 256K
buffer would have a 16K receive buffer and a 16K transmit buffer for each
port.
port.
Configuration
The serial model has a configuration menu. The parallel
model accepts configuration commands. The definition for the prefix
(default of escape @) can be changed to be up to 6 characters long. Each
(default of escape @) can be changed to be up to 6 characters long. Each
port on a serial Porter can be independently configured for any baud rate,
DTR or XON/XOFF flow control, DTR passed through, or as a buffer flow
control. The settings are saved in non-volatile memory and become the
power up settings.

Front Panel and Diagnostics
The front panel displays selected
ports, busy and data signals, and errors. Porter has a full set of diagnostics
executed upon power up and other diagnostics that can be run such as port
loopbacks and memory pattern tests. Front switches can be programmed
to be disabled in environments where tampering is discouraged.
