problem with the programmer i built a few days ago, the schematic used a db9 male as the connector, but my PC doesn't have a female slot for that connector, it only has a db9 male slot, so i used a female connector for the programmer for it. i just discovered a while ago that the db9 male and db9 female have different pinouts!how do i know which pin gives TX, RX, CTS, DTR, RTS, and GND?
this is how the db9 male and female terminals are labelled:
male: _ female:
5 4 3 2 1 _ 1 2 3 4 5
_9 8 7 6 ___6 7 8 9
Which pins should i switch?
