Re: [TUHS] Unix Circuit Design System

Yes, but earlier you pointed out that it does not emulates two wheels of the terminal. Since I have never used "draw" nor any Tektronix terminal I don't know what was the purpose of the wheels and how they are used by the program. So I thought that, if "draw" heavily relies on such feature, xterm might not suffice. 2016-01-01 15:31 GMT+01:00 Clem cole <clemc(a)ccc.com>: > Xterm can emulate a Tek terminal. > > Sent from my iPhone > >> On Jan 1, 2016, at 8:58 AM, Michele Ghisolfo <ghisolfo.m(a)gmail.com> wrote: >> >> Thank you!
