Ending Your Connection

To end your connection, log off the remote system (if applicable), enter the escape sequence (+++), and issue the ATH command.

You may want to wait 30 seconds or so after your last transmission before disconnecting to ensure any data in the Modem buffer has cleared.

Setting Up for a Non-Error Correcting Connection

The Trumpcard Modem supports the V.42 and MNP error correction protocol as its default mode. When you initiate a connection from your Trumpcard Modem to a remote Modem not supporting error correction, the remote system may respond with garbled characters or even lock up.

If the remote Modem does not support error correction, the Trumpcard continues the connection without error correction or data compression. However, as mentioned, the remote system may have already locked up. In these cases, you must break the connection, turn off error correction on the Trumpcard, and place your call again.

To turn off error correction for the Trumpcard, use the AT&Q6 command. If you wish to make this (non-error correcting) the default setting, follow the AT&Q6 command with the AT&W command.
