If I setup a serial connection and try to load up a text file (hex or basic) "/" appears on the screen followed by a linefeed at irregular intervals. It is not possible to transfer longer data correctly!
This effect is only during the serial data transfer.
First I thought that is like the described antenna ground issue described in ReactiveMicro Wiki.
I use the replica 1 plus and patched the newest Propeller Firmware .
At the moment no resistor/capacitor hardware patch installed.
Does anyone have any idea what the reason for this could be?
should I install the additional 100k resistor or capacitor?
Thanks for further advise!

You need to insert pauses between characters and lines, in the sending program. Kermit is one program that can do this.
Another example is minicom. Here it is called the newline delay and character delay. With my Keyboard Serial Terminal (see other topic) I use a line delay of 200 ms and a char delay of 20 ms. But this of course also depends on the used hardware.
Yes, this was the solution! Thanks for advice! In my case I have to take longer delays.
50ms for character and 300ms for line to load longer codes secure. 20ms was definitely too short with my board.
30ms character works, but with risc.
Best regards!

I use ZOC Terminal with Mac OS
Glad you solved it. :-)
300ms/line may still not be enough for really long INTEGER BASIC lists.
I am currently working on a ~16kB listing and, to be on the safe side, I had to increase the delay per line to 2s.
Unfortunately, in INTEGER BASIC, the longer the listing, the more the "line delay" progressively increases.
