rs 232 pin configuration in linux pc

Question

There are a lot of examples which shows on how to communicate through the serial port of the pc. But is there a way to configure the pins of rs 232? I just need to set the tx pi

Answer 1

If you are not restricted to RS232 only. You have other options

First, if you PC still have parallel port, it would be a better choice over RS232.

Or, you can use some some USB-GPIO modules. Some suggestion:

• FTDI bitbang mode
• 8 CHANNEL USB GPIO MODULE
