Is there any way of sensing the state of the RTS/CTS line of the serial interface in a C program ? I know that I could probably read the 8250 status register, but I'm looking for a solution which is hardware independent. BTW is there any other modem control signal that I can detect from a C program or shell script ? I know how to sense the DCD, but what about, for example, the DTR line? I appreciate in advance any suggestions. -Arrigo P.S. the application should be portable to several unix platforms, but will run primarily in the SCO Unix/Xenix environment. -- Arrigo Benedetti | USENET: root@pubit.sublink.ORG Via S.Agata 11, 41100 Modena - Italy | BANG: ..!rutgers!deejay!gear!pubit VOICE +39.59.216688 FAX +39.59.220727 | TELEX 512007 PUBIT I | Sublink ... the Italian **nix link ...
