vgetty fails to switch to data ... solved !

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Well, we have nailed (knock the wood) the vgetty voice/fax/data switch problem
in just a day ! This mailgroup is great. Thanks Gert, Mark, Roy, Bjoern !

So the problem really was that +FCLASS=0 should be enabled for
our modems (Supra and ZOOM). The reason I got NO CARRIER on the first try
was just the calling modem timed out - (default get carrier timeout - S7 -
is 50 sec, with five 6 second rings to wait I was always dangerously close).

Roy: of course your hack is more elegant that what I have tried by hand - 
I just send one extra AT+FCLASS=0 command in switch_to_fax_data.
I have recompiled now vgetty with your hack, thanks.

The permanent solution seems to be to propagate the knowledge of 'quirks'
into voice part ? What do you think, Marc and Gert ?
I'm very impressed how mgetty got my modem 'quirks' right !
