Speaking at any other speed will not work. (I had this problem myself). You will most likely need to start out by inserting an entry for a19200. There are entries for a9600, so just copy those. This should allow you to type tip a19200 to connect to the modem. Then you can try standard hayes commands. If this works, then the cable is fine, you just need to create a dial19200 entry. Copy the dial1200 and change br#1200 to br#19200. 3> It is quite possible that the cube is unable to handle 19200 baud. I know that ioctl standards only go up to 9600 baud. There may be problems going higher. At least that's what the man pages say. There are External A and External B, but I don't know what they mean. It is possible that you can use these to go higher. Definately put the cable on serial port a. Otherwise you will have a lot to change, and it is not worth it. >I am not sure if it is the cable, a incorrect configuration of some >UNIX file, or the Ventel modem register settings (which are a world >onto themselves).

Can you attempt to run the modem off a macintosh? That might give some clue to the problem. >Any help you could give would be greatly appreciated. >Thank you in advance. > >John N Alegre >University of Minnesota >Andante Systems Michael Rutman SoftMed P.S.

I am seriously considering buying a new 105 meg 'slab'. One small question. Is there terminal software available so I can use my modem with it? I have seen plenty of UNIX boxes that have modems hooked up for Usenet transfer and such but I was looking for terminal software (with decent vt100 emulation) for calling our mainframes and such. Question 2, has vt100 been improved in 2.0 of the OS? -- Joel Sumner GENIE:JOEL.SUMNER These opinions are q4kx@cornella.ccs.cornell.edu q4kx@cornella warranted for 90 days or q4kx@vax5.cit.cornell.edu q4kx@crnlvax5 60,000 miles.

There is Kermit out there for free. It is a wonderful tool for this purpose. With the kermit take command you can run command sequences and do all kind of other neat stuff. Kermit runs within Terminal or Stuart and thus also gives you a vt100 emulation.
