Serial Data Transmission

When I send data b/t two computers over a serial line the data arrives but
is really garbled up is there anyway to fix this? Is there a cast or do you
have to use a special read or write function? I am currently using a
straight foward read() and write() which take the fd, buffer, and size.

things I’d check

  1. That the serial cable is really working
  2. Correct baudrate and all the termios structure flags ← this is really
    important
  3. If one of your computers is a windows one, make sure your serial
    port settings are consistent with those you specify in ur QNX app
