Enter COM2 Modem Log On
ENTER COM2 MODEM LOG ON
B issue ENTER
Using the ENTER COM2 MODEM LOG ON menu,
you can define a string of initialization parameters
to be sent using the ISSUE COM2 MODEM LOG
ON menu selection. These parameters are also
sent on power-up. For a Hayes-compatible modem
set as receiver, the following string might be
used:
AT EØ QV &DØ SØ=2 X4 M1
If the first character of the ENTER COM2 MODEM
LOG ON string is a space character, no log-on
string will be issued through the COM2 port, in
effect disabling the Log On function.
Many factors are involved in choosing the current
characters for the log-on string including
manufacture, type, speed and default settings of
the modem selected. Some modems allow all
parameters to be set up before installation, thereby
eliminating the need for the modem string
altogether.
Beckwith Electric has a series of application notes
relating to communications issues. Please contact
the factory at (727) 544-2326 for further information.
