A while back someone brought up the debate regarding the existence or non-existence of insert/delete line/char functions on VT100-series terminals. Two facts mentioned were: 1. Vanilla VT100-AA terminals cannot do these functions. 2. VT132-AA terminals can. Some people, however, seemed to think that VT100s *could* do these things. Well, as I have just found out, they may be right! We had a bare-minimum VT100-AA terminal here, and I verified that it indeed (as documented) did not have the ins/del functions. We just bought the VT1XX-AB Advanced Video and VT1XX-AC Printer Port options and I installed them yesterday. The book with the printer port states that the VT100 will now have these ins/del functions. The book is right! I can now "setenv TERM vt132" on that VT100 and the insert/delete functions work as they do on my regular VT132! I'm impressed! This means that those of you who miss those functions on your VT100s need only buy the Printer Port option to get them! Note, though that the printer port requires the Advanced Video option to be installed, so you'll have to buy it if you don't have it already. I don't know if this is only true for recent printer ports, but here are the details on the one I installed: VT1XX-AC, dated 20-Sep-82 Board P/N 54-14260-00, schematic rev. F, etch rev. B. I hope this is useful to some of you. -- Bob Hoffman Pitt Computer Science

Re adding printer ports to plain VT-100's: Maybe everybody already knows this, but I thought I'd pass it along, as it burned us when we got plain VT-100s with the printer-port option installed: Adding this disables the sending of CTRL-s & CTRL-Q from the keyboard down the communications line. This is not stated clearly in the documentation (or wasn't several years ago when we got these). The option snags the CTRL-S/CTRL-Q and uses them for controlling the printer-port line. We needed to be able to send CTRL-Q down the line to tell a TAC what speed we ran at; we found out that we had to go into Set-up mode, do a Reset (key zero), and this would send a CTRL-S, for flowcontrol while the reset was in progress, following up with a CTRL-Q. That last CTRL-Q was caught by the TAC as required. Will Martin USArmy DARCOM ALMSA
