If mountng is not required, what is? The article from Moxa goes into detail about the handshaking and need to control precisely when the transmitter turns off after each transmission. At this time, that is not my problem. It may be in the future, but not yet. Right now, I cannot get the transmitter to work at all using a Linux driver. (As I said, it's OK when I load the registers directly.) Simply stated how come the command "echo "UUUUUUUUUUUUU" >/dev/ttyS2" issued after the transmitter is enabled does not produce a stream of pulses on the TXD+/- lines?
