x Fix "hangup failed" in unidialer
x Genericize tty code and/or support termios
x Fixup uucplock conventions for FreeBSD (including reference in tip man pages).
Sanity check for ttys
x Rename pathnames.h
x Qualify on USR
Use select call to merge tipin / tipout
x Finish table-driven modem driver
x Move HAVE_USLEEP to pathhnames.h
x Add variable for login and logout scripts (connect with Perl???)
x redials / redial delay (see dial shell script)
Add debug log capabilities for table-driven modem driver (command mode modem I/Owith timestamps).
Use select in modem drivers.
Consolidate consh()-derived code in cmds.c
Screen-oriented command menu?
Add external file-transfer protocol implementations to command menu (rz, sz, others?)
# $FreeBSD$
1. Rethink protection glitches on REMOTE & PHONES
files (setuid/setgid??).
