Hello all, Today I made myself a nice and simple serial cable - TX, RX and ground (I don't need anything else), and it works well when I connect 2 laptops to each other, running HyperTerminal. Unfortunately, HyperTerminal does not record serial data sent by 2 different evaluation boards (MCBSTR7/9), running Keil / ST sample code. What can be the cause of this? Can it be related to the type of wire I used? Any ideas are welcome!
Thanks in advance
A DTE is a Data-circuit Terminating Equipment - ie it is the sink and/or source of the data being communicated.
That definition, if you think about it for a moment, means nothing at all. Both devices on the ends of a RS232 link "sink and/or source data".
The distinction between DTE and DCE has long since failed to apply to the usual circumstances RS232 links are used in, mostly because modems connected to a serial port have effectively ceased to exist.
I stand by my earlier statement: If there's a PC on one end of the RS232 link, that's clearly the DTE. So whatever else is on the other end gets to take the place of a DCE, no matter whether it's a modem or not.
