7.12 Modem Settings

Device Serial device to use.
Unit Unit of the serial device. If you don't own a multiport card, this will probably be 0.
Rings Number of rings to wait for before answering.
Shared If selected, the serial port will be opened in shared mode. Use this gadget if you need to share the serial port among more than one program, for example, between STFax and a mailer.
Retry Minimum number of attempts STFax should do when sending a fax.
Redial Delay Delay between two attempts.
Init Init string for your modem.
Dial Mode This tells STFax if it should call in tone or pulse mode. If you can, you'd better use tone mode.
Dial Prefix Prefix to use in the dial command. For example, if you need to use the command "ATD0Wnnnn" to dial the number "nnnn", insert "0W" here.
Prefix String This is a command sequence that will preceed the 'D' in the dial command. i.e. if you enter X3 here, STFax will use the command "ATX3Dnnnn" to dial "nnnn".
Use Class 1 Checking this box will force STFax to use the Class 1 protocol for fax operation. This can be very useful with US Robotics modems: most of them have a defective Class 2.0 support, thus you will get many errors trying to send/receive a fax without setting this gadget.
Max 9600 Baud If your fax modem supports only Class 1 or you're using the above gadget, you may experience some unknown errors during fax transmissions. In fact, the Class 1 protocol needs a quite fast CPU in order to work correctly at high speeds (a 68020 should be enough even for 14400 bauds, but background tasks can stole too much CPU power from STFax); moreover, some modems doesn't like a speed higher than 9600.
DTR Hangup If you think that STFax is slow during hang ups, check this box. In order to have DTR Hangup to work, the modem must be configured to hang up when DTR drops. Usually this can be achieved with the &D2&Q5 command sequence, but you should check your modem manual to be sure.
