   I started looking at 9600 baud modems recently & I don't know if you
 noticed, but there has been an explosion of protocols --- TransMission
 protocols, Compression protocols, Error Correction protocols & probably
 others.
   How much of this stuff is proprietary? For example, where can I find
 out about V.42, V.42bis, & MNP-xx?
   Does anybody have an address of CCITT docs?
   Also, I notice in magazine performance tests, that there is quite a
 difference in effective throughputs depending upon the type of data sent
 ie. text, binary. What effect does sending already compressed data have?
 eg sending a .lzh or a .zip file through a V42.bis modem?

   PS.
     Does anybody have any info on MNP-8?
     Does anybody have any info on LAP-M?
