Have you any ideas or changes you might have made to the readline-1.1 package the convers 930803 compiles ok with out readline support. Or is this feature still being developed ? Thanks.

We are considering using ka9q NOS as an IP mail router for a network that will be both telephone and packet-based. We have started to tap into some local expertise here at Cornell, but I have some general questions I would like to place to peoples' expertise on the net. The network would need to support between 50-100 people initially, and I suspect that number could grow to 250-1000 in 3-5 years. You can resond to me personally at: eb15@cornell.edu or I also get the TCP Group and Packet Radio digests, and will see responses that show up there. The issues that we are trying to determine are: ka9q setup related: ^^^^^^^^^^^^^^^^^^^ 1) How well ka9q works with POP mail. Also, what version or variant of ka9q NOS works best as a POP mail server, and where to get it. 2) How well it works over a dial-up connection, and over an ethernet LAN, and any tricks that might help in setting it up. 3) Whether one can reliably use a client software package like NUPOP over a TCP/IP packet radio connection. We are considering using NUPOP or some equivalent offline reader/composer to lower connect times, and would like to be able to use the same client package for all users of the network. 4) How much direct supervision ka9q NOS needs to operate reliably, and how much technical backgound it requires of an operator. 5) How difficult it is to install and maintain a packet radio installation running ka9q NOS and what the level of technical training a sysop would need to install/manage it. Also, how well does it recover from crashes (for example, from frequent brownouts...). 6) What hardware would be recommended (from the computer itself (processor, RAM, hard disk, etc.) to the TNC, radio, antenna, etc.) for a network where we would like to be able to support 1-2 modem lines, a packet radio station, with 100-500 users (54 users initially, but I anticipate it will expand with both official and unacknowledged users). The primary use would be simple email, but will probably also include some larger document transfers (uuencoded), and it would be nice if we could also set up an ftp site and remailer for interest groups. Maximum transmission distances will be no more than 100 km (we would prefer to use UHF or VHF and avoid HF), but want a set-up that also takes into account local conditions (i.e. high temperature, high humidity, long rainy season with *heavy* rainfall, frequent lightning, etc.). Other Issues (added in case you might have any experience/answers): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1) Whether it is possible to use NUPOP to connect over a serial (dialup) line in cases where you need to place the call through an operator. (ie, if it is possible to write the connection script so that you can take the modem off line while placing the call through the operator, and then bring the modem (and NUPOP) online again as soon as you hear the carrier detect. 2) How difficult (or easy) it is to write gateway scripts to forward mail to and from other networks (ie FidoNet, UUCP, etc.) from ka9q NOS. Those are my main questions for now. If anyone has helpful comments, suggestions or resources to offer I would greatly appreciate them (particularly from people who have experience setting up such systems in developing countries). Also, anyone who would like to send me a copy of their autoexec.nos file (if they think it might be helpful or instructively related to our project), they would be welcome. You can resond to me personally at: eb15@cornell.edu or I also get the TCP Group and Packet Radio digests, and will see responses that show up there.

Seems like a step down, but who knows what goes on in the algorithm (maybe just XOR)... I didn't know what the voice quality was, but the recent report confirms my suspicion that it wasn't too good. Even military high dollar systems of the 70's were basically un-usable. Fighter pilots wouldn't use them, so they were ballast. The recent stuff is a lot better, even combined with Have Quick hopping radios. Fighter pilots will actually use it, so it must be good :-) The significant change I think was getting rid of the CVSD. The DSP vocoder technology packs the better formants into much lower rates (9.6k being the minimum I would use). --- Steve N5OWK ------------------------------ Date: Tue, 3 Aug 93 15:39:04 -0700 From: karn@qualcomm.com (Phil Karn) Subject: Micor DVP To: ssampson@sabea-oc.af.mil >The significant change I think was getting rid of the CVSD. The DSP vocoder >technology packs the better formants into much lower rates (9.6k being the >minimum I would use). Sigh. This is what I was afraid of. I know the newer DSP-based coders provide better sound quality, but I was hoping that CVSD would at least be usable. My company sells a very good DSP-based CELP vocoder, but at the price they're asking it's not yet very interesting to hams or other cost-sensitive users, I'm afraid.

Is there some way that when this digest gets refused somewhere, it doesnt make a reentry back to here. Two days ago I downloaded a 55k message because someone (nameless) decided to put an entire publication in here rather than naming an ftp site. Today, I downloaded 75k only to find that someone refused the 55k digest and thus it was re-posted. It makes it tough on those of us that have to pay for our access. Much obliged.
