Description
When the PL7 application is started in online mode, the external modem or the
PCMCIA modem card automatically dials the telephone number of the remote station, establishes the link, then responds to prompts.
Operation is then identical to how PL7 functions when directly connected to a terminal port. All functions are available, except for application downloading.
