Mac Modem Share?
Message #29924
John, Certainly I see what sort of thing you are talking about, but I am not aware of anything which does this at the present time. One of the ongoing problems currently is trying to get a modem/software program to recognize that an incoming call is FAX, DATA, or VOICE.…

Mac Modem Share?
Message #29901
John, I would like to be able to tell you the answer to your question, but I can't without understanding a few more details about the problem and the Mac environment. Certainly two programs can use the same modem on the same serial port, but they cannot do so simultaneously.…

Modem Suicide?
Message #29045
John, I would suspect the problem would be the connection at the back of the modem where the little low-voltage cable goes into the socket on the modem. This can be a little loose fitting at times. What you can do to help this is carefully pry the split on…

PPI <-> Supra??
Message #26551
John, I have not idea why the QuickMail network has the PM9600SA modems set for 4800 and ASYNCHRONOUS operation only. You will have to ask that question of the network administrator. But, the init shown in your message is forcing the PPI modem to function without any of the EC…

Won't work in Windows
Message #26523
The problem is Windows, not the modem. The Windows communications drivers are buggy to say the most for them and they do not recognize COM3 and COM4. You may be able to overcome some of the Windows problems by installing the TubroCom replacement communications drivers for the Windows drivers. TubroCom…

v.32bis!!!
Message #26144
Rod, The thing with the serial I/O is the interrupt service time. If an interrupt service routine must be performed for each character received, then 57.6 would require 57,600/10 = 5,760cps…and 1/5,760 would be: 173.6 E-6. That means that the CPU would have to be able to shove everything on…

In the XT/AT environment the standard addresses and IRQs are: COM1 03F8 IRQ4 COM2 02F8 IRQ3 COM3 03E8 IRQ4 COM4 02E8 IRQ3 Note that COM1 and COM3 share IRQ4, while COM2 and COM4 share IRQ3. This is 'built into' the original IBM architecture. (Actually, only COM1 and COM2 were originally…
