Yes after 100 posts

I am trying to make an adapter for UART.

It may look like a RS-232 serial but it's not RS-232 standard.
It is Serial comunication alright but neither RS-232 nor TTL logic levels!
It's more like TTL-serial with CMOS voltage levels.
Logic level 0 = 1-2V
logic level 1 = 10V
TTL
logic level 0 (LOW) = 0-0.8v
logic level 1 (HIGH) = 2v-5v
while the RS-232 levels are
Logic 0 = anywhere from +3 to +25V.
Logic 1 = anywhere from -3 to -25V (negative voltage)
On most PCs these signals swing from -13 to +13V.
CMOS gate circuits have input and output signal specifications that are quite different from TTL. For a CMOS gate operating at a power supply voltage of 5 volts, the acceptable input signal voltages range from 0 volts to 1.5 volts for a “low” logic state, and 3.5 volts to 5 volts for a “high” logic state. “Acceptable” output signal voltages (voltage levels guaranteed by the gate manufacturer over a specified range of load conditions) range from 0 volts to 0.05 volts for a “low” logic state, and 4.95 volts to 5 volts for a “high” logic state:
