NOTE: Using RAMEXEC to select another computer port is not suggested. This is because RAMEXEC does not provide full duplex communication so you cannot see the On Line or Busy message if you attempt to use RAMEXEC to determine whether or not you got connection to the other computer port.
Modem sharing can be achieved with a
Make the connection to the modem port by sending the Port Select Code, the module number (1 to 6) and port number (1 to 4) the modem is connected to followed by a Enter/Return or line feed character. The model 24 will respond with an On Line message if the modem is available or a Busy message if the modem is currently connected to another computer port. Proceed with your normal modem communications once you receive the On Line message from the Model 24SII DES.
It is suggested that the computer make the connection to the modem port on the Model 24SII DES from within your desired modem package. You must be in a full duplex mode within your modem package. You must also configure your modem package to communicate with the same serial port parameters that your computer normally uses to print with (i.e., baud rate, etc.).
A common mistake is to configure your communications package to match your modem's serial parameters (baud rate, word size, etc.) and not the Model 24SII's serial parameters. Keep in mind that you are physically connected to the Model 24SII DES, not the modem. The Model 24SII DES will do any necessary serial parameter conversions between the computer and the modem.
