[The difficulties in communication through RS-232C interface between monitor devices and a personal computer--the...

We investigated data output format and transmit mode of communication through RS-232C interface between monitor devices and a personal computer. The baud rate, start bit, data bits, parity bit and stop bits are listed with transmit mode of six companies' monitor devices which are now widely sold in Japan. Each monitor device has its own data output format and transmit mode, which are quite different from the others and make it somewhat difficult to import data from different monitor devices to a personal computer. We suggest that, because two or three different monitor devices are commonly used during anesthesia, some general standard should be established to make an easy communication between monitor devices and a personal computer for ordinary users.
