You have seen VA3451AD so many times ... yet here it is ! We have a Racal-Vadic Auto-dialer Model VA3451. We have written our own dialer and interfaced it with UUCP via a fork/execl. As long as we run it from UUCP the dialer hangs up after the conversation. We also use it with a few other calling programs where the dialer DOES NOT hang up after the conversation unless the other end drops carrier ! I have implemented the usual hang-up procedure of zeroed baud i.e. ioctl(dcf,TIOCHPCL,0) ... we run V7 UNIX .. or stty(B0,B0,1) which does not work. I have corresponded with a few others who wrote their own dialers and they don't seem to worry about this problem [their use is limited to UUCP only!!]. I can't spend much time on this and I would appeciate any help regarding this. uf-che!ck Kris Chinnaswamy P.S. Racal-Vadic people could simply have provided a microcoded instruction for hang-up (oh, well..) [Please mail to uf-che!ck or uf-che!root. Thanx]
