Abstract
Abstract In the present invention, a communication system is disclosed. The communication system comprises a remote computer 20 and a local computer 40, linked by communication link 12. The local computer 40 operates a conventional alphanumeric communication program 42 which receives alphanumeric data from the remote computer 20. The local computer 40 also comprises a supervisory program 56 which is Terminate and Stay Resident in memory, and which interrupts the operation of the alphanumeric communication program 42. When a particular command query is generated from the remote computer 20, the supervisory program 56 causes the local computer 40 to respond thereto, indicating the capabilities of the local computer 40 for graphical data display. When graphical data, which has been compressed and encoded in alphanumeric format is transmitted by the remote computer 20 and is received by the local computer 40, and stored in a first memory 44, the local computer 40 decodes the alphanumeric format and decompresses to regenerate the original graphical data. The original graphical data is then stored in a second memory 54 and the display unit 48 is directed to receive the graphical data and to display on the display unit 48.
