Newsgroups: comp.sys.handhelds Subject: Using HP-48 with modem Message-ID: <21978@shlump.nac.dec.com> Date: 10 Apr 91 12:26:00 GMT Sender: newsdaemon@shlump.nac.dec.com Reply-To: edp@jareth.enet.dec.com (Eric Postpischil (Always mount a scratch monkey.)) Organization: Digital Equipment Corporation Lines: 11 Has anybody used the HP-48 with a modem? The 48 controls the Transmit Data line but apparently leaves the Ready To Send and Data Terminal Ready lines unchanged. And it seems the modem expects Ready To Send and Data Terminal Ready to be asserted -- and their polarity is different from that for Transmit Data, which makes me think asserting RTS and DTR can't be done just with a couple of jumpers. Are there any solutions? -- edp (Eric Postpischil) "Always mount a scratch monkey." edp@jareth.enet.dec.com
