Looking for SVR2 XMODEM

[Jon A. Tankersley]

The usual way I get this done is lint the source I get from Berkeley and
make the required fixes.  When its an include file that is missing, I 
check for the undefined typedefs and the like and search for a similar
SysV include file and include that.

The biggest changes I ever had to make to Xmodem was in some of the 
ioctl calls, but I just #ifdef'd around the Berkeley stuff.
