[maxim232]

I have a samsung a800
& want to make a data cable
so far i find a schematic for a800 ;
@  http://www.pinouts.ru

=  http://pinouts.ru/data/samsung_t100_pinout.shtml

it seems to be incorrect ;
in the schematic :
RTS & CTS haven`t connect.(handset 04 & 05 pins)
and Vcc have been supplied from USB

if U have any info about a800 data cable, please help
