Aduino. The program constantly writes to the port. how to replace a sketch?

Iteaduino 2.2 (MEGA328P ) filled program of examples are the reading of the sensor and record readings in port, respectively, the port is always busy (TX flashing) and there is no way to fill a new program.
Tried to fill the "when" was the last one on D1 to the ground - does not help.
What are the options without using a programmer?

Write to the port can not interfere with the pouring of the program. After a reset for a short period of time triggers the bootloader. If he does not receive a request to fill - is to run the sketch. You can try to press the Reset button before/immediately after casting. Although when casting reset should be done automatically through the leg DTR on the FT232.

Tried 1-2 times 500 and a reset and power on/off. happened 1 time 3 Aduino 1/0/5 hangs at the stage "Loading" - kylee.Waelchi commented on October 3rd 19 at 02:02

Try the tips from here.
Most importantly - do not run terminal to the reception. And after perezapisi make a sketch reset for the Board.
