[net.micro.pc] vi problem with vt100 emulator "pc-vt"

kcp@bmcg.UUCP (11/17/84)

The environment is BSD 4.1 UNIX VAX 780, ibm pc running "pc-vt" 
vt100/102 emulator, connected through Hayes 1200 modem, using one 
of the latest ibm-pc termcaps (for color graphics) that came thru 
this newsgroup this week, and within .login file "setenv EXINIT" 
line includes "window=24" to allow full screen text display.  The 
problem encountered was that the ibm pc hangs up when exiting vi 
through either ZZ or :q .  Does anyone have a clue as to what is 
causing this ?  Any other similar experiences with "pc-vt" ?
