Hi.
I have been testing the HP85 serial interface. It works nicely as OUTPUT. However, I have been unable to get any input from the PC side to the HP85. Basically I have been playing with ENTER command.
For instance the following simple sentence does not get any input:
ENTER 10;X
However the following output sentence works well:
OUTPUT 10;X
The value of X is printed on the PC side.
I have been playing with different settings (baudrate, flow control,etc) with same result.
Am I missing something here?
