For example: echo -n b19200 > /dev/eai0ctl sets eia0 to 19200 baud. Not all the controls are sticky in the Unix sense so you should do this while you have the /dev/eia0 open. ------ original message follows ------ >From cse.psu.edu!9fans-outgoing-owner Sun Aug 6 16:25:01 EDT 1995 Received: by psuvax1.cse.psu.edu id <34152>; Fri, 4 Aug 1995 16:22:37 -0400 Received: from goonsquad.spies.com ([192.216.22.66]) by psuvax1.cse.psu.edu with SMTP id <34203>; Fri, 4 Aug 1995 15:32:45 -0400 Received: by goonsquad.spies.com (Smail3.1.29.1 #2) id m0seSKc-00024CC; Fri, 4 Aug 95 12:22 PDT Message-Id: From: ahm@goonsquad.spies.com (Andreas Meyer) Subject: Re: Serial port i/o, how?

I'm using a hardware setup (null modem cable to another machine) which works in DOS. In another window, 'cat /dev/eia0ctl' returns: cts dsr ring dcd dtr rts Is there anything else I need to send to the control port? Andy
