I can recive a pgm on the pc in recive ME on TNCserver, but I can't send a pgm from pc to TNC155, just BEGIN PGM and END PGM arrives and the pc just go coma-mode, anybody have the correct set up for tnc-155B??
my parameter setting is
71 :515
222 : 168
223 : 0

Try writing a program in the TNC and sending it out, then see if it will come back properly. Control does not like syntax errors, which includes extra <CR> etc.

Otherwise, make sure baud rate is the same

TNCserver don't know when to stop transmitting, keeps on reciving when the control's at an end and rady for next pgm. When it's the other way control claims incorrect data and TNCserver keeps trying to transmit.
Pgm looks alrigth on the pc, but only pgm begin, blok form and pgm end reaches the control.
all data relating to movement is lost.

Check your transfer protocol and port settings!!
I have a TNC410
Protocol is FE
baudrate 5700 on com 1
FE settings - TNC like file names (tick this box)
.xNC file name extensions (tick this box)
Just keep playing around with it !!!1

After some playing around and trying the same things twice, suddenly there was a useful connection.
I never got the TNCserver to work rigth, but we have purcased some software called CIMCO DNC-Max 5 and it works alrigth there(nuts)
Thanks for any help and interrest.
