Hi!

I've tryed to launch frdm-kl43 cdc vcom example and failed.

It looks like enumeration went ok COM17 appeared in the device management window:

But i can't get any echoed message from it:

(income messages would be black colored, violets are output messages)

according to readme file i've set:

static bool start_transactions = TRUE;

I must have done something wrong. Help me please.

example imported from KSDK v1.3 and i'am using KDS 3.0.0

Best regards,

Alexey.

Hi Iva,

Thanks for fast response!

I dont use Teraterm so can't undertand the result. When I've typed 1234 the cursor came back and did not go to new line.

Hi,Alexey.

Set the Flow Control from "none" to "RTS/CTS".

Well!

It worked! Werid that hercules has rts/cts controll too and failed on it.

I thought that

static bool start_transactions = TRUE;

would desable rts/cts control. How can it be desabled?

Thanks for responses! It helped me a lot and now I cant try to modify basic application for my usage.
