7. ieve data from the buffer for reception Most efficient data transmission occurs when the CPU is interrupted infrequently For each interrupt the CPU can then service the buffer with larger data blocks during transmission it can place a large burst of data into the buffer and during reception it can retrieve a large block from the buffer and then continue multi tasking Ideally therefore Receive triggers should be set as high as possible and Transmit triggers as low as possible However if the Transmit trigger levels are set too low or Receive triggers too high and the CPU is busy when an interrupt is called by the LavaPort a short period of inactivity may occur between the port and the modem This will reduce effective transmission reception speeds Optimum buffer settings are dependent on your modem speed your CPU speed and the amount of multi tasking that occurs while online For a fast modem and fast CPU performing few multi tasking functions set transmit triggers low and receive triggers high If multi tasking while online set transmit triggers higher and receive triggers lower Setting LavaPort Flow Control in Windows Flow Control refers to the type of signaling that is used between the modem and the LavaPort If you are connecting the LavaPort to a modem or ISDN terminal adapter use the default setting of Hardware RTS CTS flow control Software Flow Control Xon Xoff is used only for connecting the LavaPort to a
