FILE -> ADVANCED CONFIGURATION having the following options.


CAUTION: To be connected via modems with PL7 V4.1 & V4.2 should have the following drivers:

UNI-TELWAY Win2000/98 V1.4 IE08
UNI-TELWAY WinNT4 V1.8 IE15
UNI-TELWAY Win95/Dos V7.8 IE18
UNI-TELWAY Dos V7.4 IE14

Also, the use of the modem in conjunction with Magelis terminals from the port TER - AUX is not possible because the Magelis not respond by changing the Parity to None, in which case their combined use is impossible. For the solution of this problem must be used a modem that has the ability to pass 11bits (8 data, 1start, 1stop, odd parity), so then you need to configure it according to instructions and commands given in the manual.
A Modem which has the above feature is that of the company GENER.
(Schneider Alliance) model GENindus

The above description could be altered to newest versions of PL7 software and Unitelway Driver
It is the rensponibility of the developer to use the above.
