5-12 Utility Descriptions
On a desktop PC running Windows programs, such as Hyper Terminal,
determining the time zone is part of the setup of the operating system.
However, if COMM is run from a DOS box, the TZ variable still will need
to be set on the target machine.
COMM Commands
Enter most commands by pressing an Alt+key combination. Some
commands take effect immediately (such as changing the baud rate),
while others require further information (such as a
filename
) before
continuing.
If you do not want to execute a command, or want to stop a command
while it is running (such as a file transfer), press the Esc key to return to
terminal mode.
Command Description
Alt+B Sets the baud rate. This command toggles between all the
available baud rates. Continue to press Alt+B until the desired
baud rate appears on the status line at the bottom of the
display.
Alt+C Clears the display.
Alt+D Autodial allows entry of number to be dialed. Press Enter to
redial the previous number.
Alt+E Toggle echo (duplex). Press Alt+E to toggle the duplex
between full (echo off) and half (echo on).
Alt+H Hangs up if the modem is capable of hanging up with an ATH0
command.
Alt+P Toggles through the available parameters allowing settings to
be made. Esc cancels the command.
Alt+T When enabled, pressing the Enter key generates a CR/LF
instead of just a CR.
Alt+X Exits the program. This command does not drop the carrier, so
use this command if you need to do MS-DOS operations while
online. You can run COMM again without losing the carrier and
continue with telecommunications.
