BGFAX will always send at 19200, no matter what other speed you have configured in the BGFAX.CNF file. 19200 is the maximum speed that's needed, and some modems (not the Courier) require the DTE to be set at 19200, or they cannot send/receive faxes. BGFAX initializes the modem with what it feels are the best parameters needed when sending the fax. The in= strings are used during receive mode only. If you need to specify a modem command, you can insert it into the dial command, ds=ATDT just insert your commands between the AT and the DT. Regards, bgfax author

I have my FOSSIL driver at locked at 38400 BPS. Would the fact that BGFax is changing the DTE rate from 38400 to 19200 cause problems? I have noticed that I've been receiving a few faxes which have never made it through. I have not examined the logs, but I'm sure they'll reveal all. BJG> BGFAX initializes the modem with what it feels are the best parameters BJG> needed when sending the fax. How does it determine the "best parameters" when it doesn't know what sort of modem I am using? My understanding is that BGFAX.CNF is onoly required for host and send modes. Since I'm not using host mode, we can dismiss that and concentrate only on the send and rear-end modes. BJG> The in= strings are used during receive mode only. I thought they were used to initialise the modem in send mode. If said strings are used only during receive mode, perhaps you're referring to host mode.

I am running BGFax in rear-end mode behind FrontDoor 2.20c.mL to receive faxes; when sending faxes, I use send mode. I'm not using host mode at all. I understand that BGFAX.CNF is only used in send or host modes. John (japp@mpx.com.au) --- FMail/386 1.22+ * Origin: Lateline BBS - South Sydney. BBS/Fax: +61-2-9579-6564 (3:712/841)

It doesn't need to know what modem you are using. That's why they came up with Class 1, Class 2, 2.0, etc. They provide a standard AT command set to be used for fax operation. The only glitch in this is that in Class 1 and 2 more, there is no easy way for the fax program to set the flow control. The modems will usually default to software flow control only, which is a problem for DOS programs running under non-DOS operating systems. Class 2.0 fixed this glitch by making a new AT+FLO= command that allows the fax software to set the flow control without worrying about silly &H or &K commands. > I have my FOSSIL driver at locked at 38400 BPS. Would the fact that BGFax is > changing the DTE rate from 38400 to 19200 cause problems? I have noticed that It's possible, but I wouldn't think it would be that much of a problem since you are using a Courier, which doesn't really seem to care what speed you are sending/receiving at, so long as proper flow control is being used. > BJG> The in= strings are used during receive mode only. > I thought they were used to initialise the modem in send mode.

This is done because the initialization strings for send and receive modes are completely different. The in= strings are used only by /HOST mode. Regards, bgfax author
