Auto-RTS Transceiver Control
In Windows applications the driver must be enabled and disabled as needed, allowing all cards to share a
two wire cable. This card controls the driver automatically. With automatic control, the driver is enabled
when data are ready to be transmitted. The driver remains enabled for one additional character's
transmission time after data transfer is complete and then is disabled. The receiver is usually enabled, but
is disabled during transmissions, and then re-enabled after transmission is completed (plus one character
transmission time). The card automatically adjusts it's timing to the baud rate of the data. (Note: Thanks
to the automatic control feature, the card is ideal for use in Windows applications)
