Serial communication
Remote communication over the telephone network also requires a telephone modem.
The software needed in the PC, either local or remote, is CAP 540.
SPA communication is applied when using the front communication port, but for this purpose,
no special serial communication function is required in the terminal. Only the software in the PC
and a special cable for front connection is needed.
