rs323

[cool-agent]

hi, I want to convert parallel to series and then from series to parallel, so is RS323 the wright cable, how does it work
and what microchip it has and where can I find detail

is it also true while converting parallel to series you wont need a clock input and how would it convert

Serial can be either syncronous (seperate clock signal), or asyncronous, no clock signal required (but used extra start and stop bits). RS232 is generally asyncronous - often using a UART (Universal Asyncronous Receiver Transmitter).

If you want to use hardware chips you might try looking for HD6402, which I seem to recall was a common number back in the distant past
