When you’ve set up an RS232 (Serial) connection, but aren’t getting a login prompt, there are several things to check:
- Make sure you’ve chosen the right serial port. For example, TinyTERM defaults to COM2. If your PC only has one serial port, COM1, you’ll need to change the default.
- Verify the communications settings. The baud rate, parity, word length and stop bits all need to match the port settings on the host computer, for the host port your PC is connected to. Each port on the host can have a different communication setup, though that’s uncommon.
If everything is set correctly, but you’re still not seeing a login prompt, you need to test the connection with another application. For example, there is a program included with Windows versions up to XP (but not Vista) named HyperTerminal. Regardless of the application or operating system you use, configure the connection the same as in TERM or TinyTERM.
If everything is set correctly in the other application, but you still don’t get a login prompt, then the problem isn’t in the terminal emulation software. It may be a problem in your PC’s serial port, in the cable connecting you to the host, or in the host’s serial port. You’ll need to test the hardware for failures in that case.
