| + | **Cannot communicate on serial terminal with the vmodem script**\\ | ||
| + | After running the Virtual Modem script on the Raspberry Pi, and connecting it to your computer via the USB-to-Serial adapter and a null modem cable, you should be able to fire up a simple serial terminal on the computer and issue a few Hayes commands to ensure connectivity. Hayes commands are a common way to communicate with Modems, and by typing AT and pressing enter in the terminal, you should see an "OK" response. The vmodem script also recognizes other commands, such as HELP which should provide a short list of recognized commands). If you receive a garbled response after typing AT or HELP, your serial speed settings may not be the same on both ends. Make sure you have adjusted the communication speed to match. If you receive no response whatsoever, you might have a problem with the USB-to-Serial adapter or you may be using an older UART on your computer (see section 2 for more on this). If you're still unable to communicate with the VModem script, feel free to join our Discord channel (see bottom of page for link) for further support. Simple tutorials can only go so far... :) | ||
