Question

I am trying to setup a faxing on port server ts 4 , with latest firmware, multimodem mz5656, and using the adapter i made from the port server modem adapter specs. for some reason fax fails during transmission. I am using linux centos 5 and hylafax. I f i use the same system with etherlite and etherlite modem adapter it works. but with port servers i couldnt able to make it work. I checked the modem log and it shows this.

it fails at this point where it says [8:<8a>OÃ<8a><8a>OÃ<8a>]

anyone knows why?
Thanks

If you connect directly to the tty port using cu, minicom, etc...and issue those AT commands are you successful or do you see errors.

Based on the garbage characters seen, you might need to train the modem speed:

If the Modem has DIP switches, set them to the async default position.

The command sequence for the modem should be:
​
at&w1z -- reset modem to factory defaults
and read DIP switches if present

at$sbs0=1&w -- locks DTE speed at port speed
and stores to NVRAM

If you are using 8 wire cabling, make sure the altpin setting is applied to the port on the PortServer unit.
