Onboard Serial Ports (1, 2, 3, 4)
Normally, the main board’s I/O chips will occupy a certain portion
of memory space. For each I/O device the computer provides an
I/O address. The more devices attached the more address needed
to organize the memory storage areas. If all the I/O devices were
run through the same address, your devices would come to a near
halt. By providing the end user with four serial ports this allows
devices to run more efficiently if needed.
Selections of logical COM port addresses are as follows. ( 3F8,
3E8H, 2F8, 2E8H)
IR Transmission Delay

changed from RX mode to TX mode.
