Yeppers, spent this weekend figuring it out. You need to assert
CTS/RTS or whatever on the port for it to work (at least on our
machines.. Intel MB 120 MHz Pentiums)--even though the kernel boots
fine without the handshake, the bootblocks still seem to require
this (anyone want to "fix" this, perhaps with an #ifdef? My
own knowledge of i386 assembly is inadequate (thankfully?)...)
I pulled out the soldering iron and connected pin 4 from the terminal
to pins 5 and 6 on the PC side (DB25--there's a DB9/DB25 converter
thrown in there and a null modem too...)
