To choose the 1.0 protocol use +the link0 flag with +.Xr ifconfig 8 +or in your /etc/hostname.plip? file. In order to use the 1.0 protocol +the kernel has to be compiled with COMPAT_PLIP10. +.Sh NOTES +To connect two computers a "Laplink parallel cabel" is used: +.sp +.TS +allbox tab(|); +c|c|c|c +l|n|n|l. +Signalname|Con A|Con B|Description +Data 0|2|15|Data out 0 +Data 1|3|13|Data out 1 +Data 2|4|12|Data out 2 +Data 3|5|10|Data out 3/Wake out +Data 4|6|11|Data clock out +/Ack|10|5|Data in 3/Wake in +Busy|11|6|Data clock in +No Paper|12|4|Data in 2 +Select|13|3|Data in 1 +/Error|15|2|Data in 0 +Gnd|18-25|18-25|Ground +.TE +.sp +In both protocol versions ethernet frames are used. The 1.0 protocol assings +an ethernet address of the form FD:FD:ww:xx:yy:zz to the interface. The 1.1 +protocol uses FC instead of FD. ww, xx, yy and zz are taken from the internet +address ww.xx.yy.zz of the interface.
