G'day Bill,
 
 BG> Possibly because you did not disable MNP5, although the 
 BG> difference should not have been that great.  The simple fact 
 BG> is that MNP's 256 byte frames suffer from less protocol 
 BG> overhead than LAPM's 128 byte data frames, and the overall 
 BG> cps rates under MNP4 are measurably faster as a result.  
 
 AM> Yep, tried MNP, disabled all compression and got 3320 cps, 
 AM> with 256 byte blocks which is about a 40cps improvement, but 
 AM> I had no compression. I'm going to stick with V.42 and 
 AM> V.42bis for the moment.

 BG> Might as well, as even on ISD calls, the saving is minimal 
 BG> as the overall difference is still fairly marginal.
 
 AM> What CPS rates do you get on your Courier at 28.8K with V.42 
 AM> and V.42bis? (ZIP file and Zmodem)

 BG> Under LAPM with BTLZ enabled, usually somewhere between 3300-3350 cps.

BLTZ? How can I enable that?
