Trouble-Shooting Difficulties in Communicating
If you are having difficulty establishing and maintaining communication between
Pacterm and your TNC, here are some points to consider in addition to those cov-
ered on the “Pacterm Cannot Communicate” screen.
Problem: Go to Terminal Screen, but Nothing Happens
One possibility is that the current COM port does have a device on it, but it is not
a TNC. It might be a mouse or an internal phone modem, for example. To see if it
is a mouse, go to the TERMINAL Screen, start moving your mouse and see if se-
quences of characters appear as you move the mouse. If so, change the COM port
setting in Pacterm and try again.
Problem: Your Computer Freezes Up
When Pacterm gets the go-ahead signal for communicating, it will act on the
assumption that the signal is from your TNC. There is no way Pacterm can verify
that the signal is actually coming from your TNC and not from another
device on the current COM port (e.g., a mouse, or an internal phone modem).
So if the device on the current COM port is not a TNC, Pacterm will be running
under a misunderstanding and, in this case, your computer may “freeze-up,”
requiring you to turn it off, re-start it, and take steps to correct the problem before
running Pacterm again.
Problem: You Are Getting Bad or Intermittent Data
Many PC compatible computers are designed with a built-in potential conflict
that may cause a problem: Both COM2 and COM4 (and both COM1 and COM3)
may use the same interrupt (IRQ) mechanism to get the attention of the computer.
This means that if devices on both COM2 and COM4 (or both COM1 and
COM3) are sending signals to the computer at the same time, this can cause
problems for programs, such as Pacterm, that use either COM port. If you are
getting bad data, check to see if you have another device that might be getting
confused with your TNC (on COM4 if your TNC is on COM2; COM3 if your
TNC is on COM1) and make it inactive or remove it while using Pacterm with
your TNC.
