= SUMMARY =

Pocket modems are a special class of modems that are quite small in size. Typically, they draw their operating power from the computer’s serial port and from a telephone line.

Works can use these modems; however, there may be some special considerations required to enable them to work properly.

= MORE INFORMATION =

Pocket modems are usually turned off. When a communications program, such as Works, begins to communicate with the modem, the modem turns itself on.

While the modem is in the process of turning itself on, it cannot accept characters that are sent to it from the computer. When Works sends a dialing command, such as “ATDT 555-1212,” the modem may receive only the string “D 555-1212” or “5-1212.”

Workaround
A workaround for this problem is to use the simple modem setup string of letters, AT, preceded by a number of spaces. The spaces will be ignored by the modem, and the AT command should return the status “OK” from the modem to the screen, informing Works that the modem setup was successful.

It is recommended that at least 12 spaces precede the AT command. This should give the pocket modem ample time to power up and be prepared to accept commands.
