Everything will work as before - only if two SysVr4-uucico's connect,
file transfers will be restartable.

During initial handshaking the two uucico's exchange some flags,
which indicate their capabilities. Since Waffle answers with no options,
no attempt will be made to restart file transfers.

A sample init for Waffle calling SysVr4:

System Answer
SysV   Shere=SysVr4
Waffle Waffle
SysV   ROK

SysV1 calling SysV2:
SysV1  Shere=SysVr4
SysV2  SysV2 -R
SysV1  ROK -R

Only if both systems agree on using the option '-R', file transfers
can be restarted.

BTW: After reading through the docs for Taylor UUCP it seems, that the
'G' protocal is supported by SysVr4 only, and it's completely compatible
with the 'g'-Protocol. 'g'-Proto _should_ be able to do more than 64
Bytes per window, but most implementations are limited to the 'standard'
7 windows with 64 bytes :-(
