This command is used to send ASCII printable data from the 

COM1

 or 

COM2

 or disk file to a specified

communications port. This is a one-time command, therefore the data message must be preceded by the 

SEND

command followed by the <Enter> key (<CR><LF>) each time you wish to send data. (Remember to use the

MESSAGES

 command to disable error reporting whenever two GPSCards are connected together via the 

COM

 ports.)

Scenario:

Assume that you are operating GPSCards as reference and remote stations. It could also be assumed

that the reference station is unattended but operational and you wish to control it from the remote station. From the
remote station, you could establish the data link and command the reference station GPSCard to send differential
corrections.
