[asterisk-users] how to set iaxmodem receiving speed

[Larry Moore]

Read the subject line more closely.

Tested receiving too,

I set the Send & Receive speed of the receiving analogue modem to that 
below, the log file on the sending modem (iaxmodem) reported it capable 
of 9600.

May 16 21:32:04.28: [ 2335]: REMOTE best rate 9600 bit/s
May 16 21:32:04.28: [ 2335]: REMOTE max A3 page width (303 mm)
May 16 21:32:04.28: [ 2335]: REMOTE max unlimited page length
May 16 21:32:04.28: [ 2335]: REMOTE best vres R16 x 15.4 line/mm
May 16 21:32:04.28: [ 2335]: REMOTE format support: MH, MR, MMR
May 16 21:32:04.28: [ 2335]: REMOTE supports T.30 Annex A, 256-byte ECM
May 16 21:32:04.28: [ 2335]: REMOTE best 0 ms/scanline
May 16 21:32:04.28: [ 2335]: USE 9600 bit/s

Perhaps the issue is with Hylafax.

Setting the Transmit & Receive strings to "!24,48,72,96" seems to yield 
the most reliability in transmission

Cheers,

Larry.
