SERIN confusion on receiving a string of characters.

[HenrikOlsson]

What sort of USB-to-serial is this?
The fact that you're using a 22k resistor indicates the converter is an "USB-to-RS232" converter which means you should use N9600 (Mode 6) when the RS232-signal is connected (via resistor) to the PIC. Your code, on the other hand, uses T9600 (Mode 2) indicating that the converter is "USB-to-UART" in which case the resistor isn't really needed. Also, make sure you have the GND of the converter connected to GND of PIC and - obviously - that you have selected the correct baudrate in whatever terminal program you're using.

As usual, get the basics going first BEFORE you try to fill arrays, using wait characters, timeouts and so on.

Decoder routine and other code works fine. I'll check other things too later. I already tried setting mode 6, no difference.

The USB<>Serial converter is common one, based on CH340 chip.

Issue solved.
While manual says "Pin is automatically made an input."
In fact it does not, so I made that pin an input via TRIS register and now (mode 6) works fine.

Now how to change above code, so it displays text immediately after pressing the enter, not waiting for 8 characters to fill in?

Page 211 of the manual for the SERIN2 command

Use STR ArrayVar\n{\c} where the c is the 13 (enter).

Like this?

serin2 portb.6,16468,[WAIT(13),STR textline\8]

It works, but with big delay and not repsonding to "ENTER"
actually, it only works when 8 characters are typed in a row quickly...

More like this

serin2 portb.6,16468,[STR textline\8\13]

It will exit either filling 8 characters in the textline or earlier if you hit enter

If you want also to start filling textline after first enter then use this (not recommended though):

serin2 portb.6,16468,[WAIT(13),STR textline\8\13]

because serin may get confused which enter is, first or last. Better use different character for start and finish.

Wow thanks!
it works like Charm!
