[hylafax-users] HylaFax does not disable copy quality checking by modem

["Vyacheslav Frolov" <v.frolov@globalone.ru>]

I use ZyXEL U1496E  V 6.18 P with config zyxel-1496e-2.0

While starting faxgetty there is log:

Mar 14 17:35:45 fax FaxGetty[7611]: <-- [9:AT+FCQ=?\r]
Mar 14 17:35:46 fax FaxGetty[7611]: --> [11:(0-2),(0-2)]
Mar 14 17:35:46 fax FaxGetty[7611]: --> [2:OK]
Mar 14 17:35:46 fax FaxGetty[7611]: MODEM Supports 1D+2D copy quality checking (but not enabled)

It seems that HylaFax expect that by default modem does not check copy quality but

# cu -l ttyD7
Connected.
atz
OK
at+fclass=2.0
OK
at+fcq?
1,0                    - by default modem checks copy quality
OK

So sometimes there is log like this:

Mar 15 18:19:20.49: [10740]: <-- [7:AT+FDR\r]

Mar 15 18:19:23.14: [10740]: --> [5:ERROR]

I fixed that by

Class2Cmd:              AT+FCLASS=2.0;+FCQ=0,0

but it seems that HylaFax (itself) should issue AT+FCQ=0,0 when
"MODEM Supports 1D+2D copy quality checking (but not enabled)"

BTW: ZyXEL U336RE V 1.18 has the same issue.
