List-Id: Computer Old Farts Forum Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: From: segaloco via COFF Reply-To: segaloco Howdy folks, just finished an exciting series of repairs and now have a DEC= VT100 plumbed into a Western Electric Data Set 103J.=C2=A0 I was able to s= upply an answer tone (~2250Hz) at which point the modem began transmitting = data.=C2=A0 I could then pull the answer tone down and the connection remai= ned, with keypresses on the VT100 properly translating to noise on the line= . Really all I have left is to see if it can do the real thing.=C2=A0 I'm kee= ping an eye out for another such modem but in the meantime, is anyone aware= of any 300-baud systems out there in the world that are currently acceptin= g dials in?=C2=A0 I don't have POTS at home but they do at my music practic= e space and if there is such a machine out there, I kinda wanna take my ter= minal and modem down there and see if I can straight up call a computer ove= r this thing. I've got other experiments planned too like just feeding it 300-baud modem = noise to see if I get the proper text on the screen, that sort of thing, bu= t figured this would be an interesting possibility to put feelers out for. On that same note, if I get another modem and a stable POTS number to expos= e it via, I'm considering offering the same, a 300-baud UNIX-y system folks= can just call and experiment with (realistically probably a SimH machine w= ith the pty/tty socat'd together) - Matt G.
