A Complete Send and Receive Fax & Data Modem

Xecom 

Command Line - Commands may be joined in a single command line up to 40 characters

long. Commands are executed in the sequence they appear. Spaces may be inserted into

the command line to improve readability. Spaces do not fill space in the command buffer. A

carraige return terminates the command line and causes the commands to be executed.

Register S3 allows the user to select a character other than a carriage return to terminate the

command line.

Command Buffer - No more than 40 characters, including the AT prefix, may be loaded into

the command buffer. If the command buffer overflows, the modem issues an "ERROR"

result code and commands are not executed.

Command Line Editing - The backspace can be used to edit the command line before it is

executed. Hiting the backspace key, or Control and H simultaneously on some systems,

erases the previous character in the command line. All of the characters in the command

line can be erased escept for the "A" and "T." Register S5 allows the user to select another

character other than a backspace to edit the command line.

Re-Execute Last Command - The A/ command causes the modem to reexecute the last

command line. This is the only command which does not require the "AT" prefix.

Ommitted Parameters - Most commands include a parameter which determines how the

functions will be set. When the command parameter is omitted from the command string, it

is assumed to be a 0.

Escape Characters - A 3 character escape sequence maybe entered while in data mode to

switch the modem into command mode while on line. The escape character, set by Register

S2, must be entered 3 times in succession within a 1 second guard time to execute the

escape. The default escape sequence is "+++."

Result Codes - The modem issues a result code after each action. Result codes may be

provided as full words, numeric codes or may be disabled all together. Each result code

ends with a carriage return when numeric resul codes are chosen. When full word result

codes are chosen, a Line feed and Carriage Return preceed abd follow each result code.
