HT12E and the serial port??

Greetings,

In my last query, i have mentioned the usage of the TLP434A to transmit data from the computer (VB6 application) to the RLP434A. I just found out that i might need a HT12E encoder. i was wondering if it was possible to connect the HT12E to the serial port, so that i could send the data to the HT12E through the data out pin and then from the HT12E to the TLP for transmission.

Anyone have any clue or links to what i might be taking about, please help. I really donno much and it would be a tonne of help.

Thanks and regards
