That helped! In addition:

• I switched to a regular serial cable and used an old GRiD laptop running ProComm Plus.
• I changed the code just a bit:
  
  Code:
  

  10 LET E$="hi"

This way, it initializes a string variable, and now I can send messages from the GRiD to the 9826. I'll have to learn more about strings to see if I can capture more than 16 characters at a time.

However, I still can't transmit from my laptop using the USB serial adapter. But now I know there is some kind of hardware misconfiguration. Thanks for your help!
