use of cyclades-serial-client with CISCO AS
by Francesco Ciacca (Consultant) 28 Jan '05

28 Jan '05

Hi Peter, if you remember, i wrote you some time ago for a question about using cyclades-serial-client in conjuction with sercd. Thanx again for your help at that time. Now my company bought a CISCO AS5350, and that device will be used in my project. To be more precise, we want to use it from the linux client by means of the cyclades-serial-client. As i said, everythings worked for me until we used the sercd as server, and we were confident to be compliant also with the Cisco AS as long as they both use RFC2217. But the first when i tried to connect the cyclades-ser-cli to the CISCO AS i discovered that the solution doesn't work anymore. I tried to look in the log, the code and around the web (reaching mostly content from you) and now i think that there are some difference on the RFC2217 implementation. First of all, speed : the Cisco (as also i read in a newsgroup thread) report speed not as it receives it. Other differences: command-notification sequence: the cyclades-ser-cli blocks waiting for a response from the server, but in the case of SET_MODEMSTATE_MASK and SET_LINESTATE_MASK the Cisco doesn't send any notifycation back. I modified the code ignoring the speed sent back by the Cisco and making the two commands not blocking, but still it doesnt'work. Have you ever tried a CISCO AS as a server form cyclades-serial-client? Do you now what are the big differences between it and sercd? Con you help me in some manner to make cyclades-serial-client work also with CISCO AS? Best Regards and thanx a lot in advance Francesco Ciacca

Modem pooling

Hello, I just downloaded your software, and before I get too far down the path of installing it, I was wondering how it handled multiple modems and pooling. I'm currently using Dialout/IP Server, but it looks like that isn't being maintained anymore, and I'd like to have something on a more stable linux platform, instead of the WinNT we have now. Dialout/IP assigns port 7001 on up for modems, and it looks like 7000 for the hunt group. Any ideas on how to handle this? I've got 8 modems I want to have available to my users. Thanks! ========================= Scott Mace Security Administrator Travelcenters of America 440-808-4318 mace.scott(a)tatravelcenters.com =========================

I have it running, now how do I use it o ?

I can run sercd and it will output what is on the serial port. Now I want to connect to sercd over the network. I'd like to use telnet but I don't know which port to use. I looked through the README and the source and didn't see anything about a port to use. I used netstat to determine which port it was listening on but that didn't tell me anything. It looks like sercd isn't listening on a port so how does it communicate over the network? Thanks, Tom
