I am playing with Gnuucp and trying to add dialer support for VENTEL modems. Currently, it only supports HAYES protocol. My problem is that I cannot get the modem from its quiescent state into interactive mode. The manual states that to wake it up, you _type_ two carriage returns at it. From a VT100 emulator, I can wake it up just fine, but not from a program of mine. So: Is there some special way to open the serial port on the Amiga? (Other that whatever way it is using now) Is there something bizzare that must be done to VENTELs? I know that under Ultrix, you just set the ACU to type VENTEL and magic happens. Does anyone know what gets sent to the modem under Un*x? Thanks, -ethan -- Ethan R.

Ahem. The Amiga's OS is not UNIX. I know, I have a bunch of Amigas. I also have some 3B1 systems. Quick question: you attempting to do this from a C program? If so, the easiest way to assist you is to point you at the source code for either the COMM or the Amiga-C-Kermit programs. If you need source, let me know. You can ALSO simply open the SER: port as you would a file, and send some chars its way ... that'll wake up your Ven-Tel. I know, I have a Ven-Tel (and ARK and CTS too). Thad P.S. The newgroups "comp.sys.amiga.tech" is NOT official, and who knows in what bit bucket your message ended.

To wake up a VENTEL, you must send two CRs (^M, not ^J). These
must be sent about 0.5 - 1.0 seconds apart with no intervening characters.
You can't send NULs and you can't send them right on top of each other.
Other than that, there is no real trick.

(I can't help you with the specific system, as I learned to do
this from (gasp) CP/M-80. Maybe newer VENTELs are different. )
