However, if the port is driven by NON Moxa-pr ovided dr iver , such as standar d ser ial dr iver , or Moxa drivers other than Windows NT and 95/98, such as DOS and Windows 3.x, the real working speed is equal to 8 times of the displayed speed. For example, a port, if set to Normal Speed Spectrum with 38.4 Kbps, will work at 38.4 Kbps for sure; while a port, if set to High Speed Spectrum with displayed speed 38.4 Kbps, will actually work at 307.2 Kbps (38.4 Kbps¡Ñ8).

The following is the 8 times speed mapping list for quick reference purpose, par ticular ly for DOS and Windows 3.x dr iver .

INT Vector Enter the interrupt vector I/O address for all ports. I/O address for interrupt vector is from 00000H to 0FFFFH. Interrupt vector is one byte of I/O address, in which each bit is used to indicate the occurrence of interrupt for corresponding port.

There are two modes for the Industio CI-134 Series driver. One is using interrupt vector, the other is not. To use interrupt vector, type in the hardware interrupt vector I/O address. If not using interrupt vector, type 0 or leave blank as the interrupt vector. Driver employing interrupt vector scheme is supposed to have better performance than employing polling scheme.
