Plus II as a remote-
access 2400 bps
modem
You can use the Ven-Tel 2400-33/Plus II modem as a remote-
access modem operating at 2400 bps. Use “Setting the switches
on the Ven-Tel 2400-33/2400 Plus II modem” on page B-25 for
both local and remote use.
To configure the Ven-Tel 2400-33/2400 Plus II as a remote-
access 2400 bps modem, follow these steps.
3Enter at&f &d3 &c1 1 3 s0=1 s64=1 s14=12 <Return>.
The cursor returns to “A” on the same line.
Note:
If the console port speed is set for 1200 bps, configure
the modem with 0 instead of 1.
This step disables the echo of the modem. Enter the following
command carefully, because you will no longer see your input
on the terminal screen.
4Enter ate0 &w <Return>.
5 Turn the modem off, wait 10 seconds, then turn it back on.
