Does FlexFAX work with following configuration:
Note:
The following information relates FlexFAX and I'm not sure
if and how it works with HylaFAX (Matthias Apitz).
How to Use FlexFAX with a NetBlazer by C. Slater, Rev 0.1, 8/24/93
Configure your NetBlazer.
On the NetBlazer running version 2.1, I set up my modem on line01 with these line commands:
Start nd:
Telnet to the NetBlazer and run line trace. (E.g. trace 01 on). tcpcon should make a connection to line01 and line01 should move to state "TALK". The line parameters should now look like this:
Get out of tip (or whatever). Line trace should show the line moving to Idle and then back to TALK.
Almost ready to go. Now you need to make one source modification.
faxd goes nuts lowering and raising DTR to make sure that DTR really comes back on, it closes and opens the tty file. This is bad for the raw TCP connection that makes the "nd-NetBlazer" team work. FlexFAX does all this for good reasons, but those reasons don't apply to this configuration. In my copy, I took the reopen out of of the FaxModem::reset(long ms) function in FaxModem.c++.
The code I took out out looks like this:
At this point I could send FAXs to various number using sendfax.
Notes:
I used a WorldBlazer in my test, but I don't think it matters. Any modem that works with FlexFAX should work with the NetBlazer in this configuration. I used FlexFAX 2.1 and the 2.2beta041 code.
The dtrtime value (the time the NetBlazer waits for the modem to boot) of 200 milliseconds is an order of magnitude shorter than it needs to be in normal worldblazer/netblazer configurations. I faxd does its own waiting and it takes a while for flexfax/nd/netblazer raw TCP will allow to get going. This gives the modem the extra 2.5 seconds it needs to finish booting.
Many people would like a more general solution that allowed them to use a single modem for anything (SLIP, FAX, etc.) without manual reconfiguration. I don't know how to do this, yet.
I am sure I missed something in the instructions, so when you find it let me know.
Thanks! -charlie
