It is a 16 pin IC with the transmitter pins connected to the microcontroller and the port such that the input transmitter pin get TTL input from the Microcontroller and the output transmitter pin supply output to the RS232 port. The receiver pins are connected to the RS232 port such that t...
Technically the RS232C is -3V to -12V for logic 1 and +3V to +12V for logic 0. The transmitter circuit uses PNP transistor, BC557. While ark s e t he TxD signal is logic 1, Q1 turns off. TxD (pin3) then provides -9V (depends on what converter chip being used for COM1, ...
From DS30292B-page 33 (the '873 datasheet section 3.3 PORTC and TRISC Registers): When enabling peripheral functions, care should be taken in defining TRIS bits for each PORTC pin. Some peripherals override the TRIS bit to make a pin an output, while other peripherals override the TRIS bi...
Presence of a 25-pin D-sub connector does not necessarily indicate an RS-232-C compliant interface. For example, on the original IBM PC, a male D-sub was an RS-232-C DTE port (with a non-standard current loop interface on reserved pins), but the female D-sub connector on the same...

It's worth noting that not every 25-pin D-sub connector has an RS-232-C compliant interface. Some PC manufacturers opt for non-standard signals and voltages on certain pins of their PC COM port pinout. On the original IBM PC, for instance, the female D-sub connector was used for the...
