Tips on Modem Setup

Many modems are shipped from the factory to force Carrier Detect (CD) and Data
Terminal Ready (DTR) high (TRUE). Sometimes, this can confuse communications
programs into thinking the modem is on-line at all times.

One solution is to change your modem setup to follow the true state of CD and
DTR.

For most Hayes compatible modems the characters &C1&D2 should be included in
the setup string unless you have changed the dip switch settings.

&C1   (DCD) Data Carrier detect line from the modem to the computer functions
      normally so the computer is able to tell if the remote modem is still
      present, or if it has hung up.

&D2   Modem pays strict attention to DTR and hangs up the phone when the
      computer drops DTR.


The following commands MUST be either present in your init string to the
modem, or stored in your modems default. Courier reads the result codes
from your modem, and expects them in 'English.'
