Comment on A Mystery of Unix HistoryparentComments−jgoerzen6yI have a vt420, vt510, and IBM3151 and not one of them do RTS/CTS like we'd expect. The vt510 can apparently do that on the DTR/DSR pins, but the vt420 and below cannot, and neither can the 3151.−therealcamino6yThe VT220 had RTS/CTS. You had to turn it on in the menus, and you needed a cable with all the pins connected, but it worked fine.http://www.bitsavers.org/pdf/dec/terminal/vt220/EK-VT220-TM-...
