Hi, I want to assign the program's stdin in the IDE to COM1 on my PC, so I do
>ASSIGN COM1 < SIN
*** error 127, line 2: Com channel not opened, use MODE command first
>MODE COM1, 9600, 0, 8, 1
COM1: not active.
There is a slightly wrong syntax in one place of the user's guide. MODE has no comma after the COMx identifier. Correct is: MODE COM2 19200, 0, 8, 1
