you can increase the number of connections (up to 32) or the number of Async Gateways that you

Selecting a Serial Port Configuration

After you determine the number of connections you need, you must arrange for a serial port and a
modem plugged into an analog phone line for each connection. If one or two serial ports are
adequate for your GroupWise message traffic, you can use the existing serial ports on the server.
If message traffic is heavy, you may need to increase the number of connections. The Async
Gateway supports 4-, 8-, 16- and 32-port communication through a multiport serial expansion
board or multiple, daisy-chained boards.

Gathering Modem Information

In order to attach a modem to a serial port, you need to know the following information about the
serial port and the modem:
Serial Port Name: The name of the serial port as specified by the device driver (for example,
com1).
Modem Name: The name of the modem definition for your particular modem. If your system
does not have an appropriate modem definition for your modem, see
a Modem Definition," on page
Baud Rate: The transmission speed of an asynchronous modem measured at the port to which
it is connected.
Flow Control: The communication method between the modem and the port. The Async
Gateway uses the standard value CTS/RTS. The modem raises the CTS (Clear to Send) signal
when it is ready to receive data. The serial port raises the RTS (Request to Send) signal when
it is ready to receive data.
Character Length: The number of bits in a byte, typically 8.
Parity Bit: A method of checking that data has been transmitted accurately. You do not need
to use a parity bit for the Async Gateway unless you are connecting to a system that does not
support an 8-bit data path.
Stop Bit: A bit that indicates that a byte has just been transmitted. Every byte of data is
preceded by a start bit and followed by a stop bit. You can use the standard 1 stop bit for the
Async Gateway unless you are connecting to a system that uses 2 stop bits.
