SERIN confusion on receiving a string of characters.

[CuriousOne]

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!

[Ioannis]

Great !

But if you need start character better be different than stop character.

Tried to use this with arduino, instead of RS-232. But it does not work, since polarity is inverted.
Added simple 1 transistor inverter and everything is fine, but maybe it is possible to modify PBP settings for SERIN2 to accept "inverted" serial data?
