Recently I posted a request for info on the uucp trace format ( uucico -x9 )
to this newsgroup. Since I now got my 9600 modem working I thought I tell
you all how.

  After I connected my 9600Bps modem to my unix system and dialed in to my 
Newsfeed I realised that it did not work very well. I got 3 files off the 
Backbone and then it fell over with FAILURE IN INPUT/SLAVE MODE.

  I read the exelent article posted recently on the UUCP protocol ( originally
by MR Chesson and others ) but it could not explain the sudden loss of 
connection with resulting uucp alarms that I was experiencing.

  What saved me was Tim Endres remark about the nesseity to ensure that all
XON/XOFF flow control had to be disabled, that it in fact insted was 
nessesary to use RTS/CTS flowcontrol between the DTE/DCE since uucp g
protocol handles all other flow-control / error correction nessesary.

  What surprises me now is that 2400 Bps does'nt seem to care less wheter
XON/XOFF is disabled or not.  I suppose it is unlikley that any buffers gets
filled at 2400 Bps.

Its been really useful to read this group the last couple of weeks, I will
continue to do so.

Thanks, Lars.
