Sometimes you need to hold down one key on the computer while pressing another
key. This is indicated by giving the name of the first key, then a plus ‘+’, then the name
of the second key. For example, “Ctrl+C” means “press the key labeled ‘CTRL’ or ‘Ctrl’
(i.e., the “control” key) and, while continuing to hold it down, press the ‘C’ key”. Multiple-
key combinations that generate a single character are shown in angle brackets, like this:
<Ctrl+C>.
Conventions for the MT1200 commands are covered in the “Command Reference”
section of this manual.
Trouble-Shooting Difficulties in Communicating
If you are having difficulty establishing and maintaining communication between
HyperTerminal and your TNC, here are some points to consider.
Problem: Go to Terminal Screen, but Nothing Happens
One possibility is that the current computer COM port is connected to a device, but that
device is not your 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 sequences of random or garbled characters appear as you move the mouse. If so,
change the COM port setting in HyperTerminal and try again.
Another possibility is that the MT1200 has already been programmed with a different
baud than the one set in the terminal program. You can try changing the baud in the
terminal program, or you can use the self-test jumper (J11) to erase the current settings
in the MT1200, forcing the MT1200 to try its Autobaud routine.
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
HyperTerminal, 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 HyperTerminal with your TNC.
Problem: Your TNC Stops Behaving Normally
HyperTerminal is intended for use with a TNC in TERMINAL Interface Mode (or, less
often, in BBS or GPS Interface Mode), but it may receive data from the TNC in any
Interface Mode. Non-response, garbled data, or partially garbled data may indicate the
TNC has been switched to KISS mode and needs to be switched back to TERMINAL.
