Serial port (RS232)

You can connect HostAccess directly to the host via a serial cable, in almost the same way as a normal terminal. The connector on the back of the PC may be different from the one used on a standard terminal. To use a standard terminal cable, you may need a 9 pin to 25 pin adapter between the PC and the terminal cable. You may also need to cross over pins 2 and 3 on the connection.

The options are described below:

Port	Use to select your communications port number (COM1 to COM4).
Speed	Select to set the correct data transfer speed (in baud).
Parity	Use to select parity type for your connection.
Data bits	Use to select the number of data bits in each byte.
Stop bits	Use to select the number of stop bits.

To define how HostAccess tells the host that its input buffer is full and how HostAccess is told by the host that it can receive no more characters, both HostAccess and the host system must use the same flow control protocol. Select the options in the Inflow and Outflow boxes as follows:

None	Select to do nothing (and risk losing characters).
Xon/Xoff	Select to use XON/XOFF software protocol (can only be used for serial ports).
RTS/CTS	Select  to monitor RTS/CTS control signals. RTS/CTS will only work if you have an appropriate cable between the host and the PC.
