I >can't seem to get it to work at those rates without getting lots of errors Certainly: I'm using it reglarly with my Coourier HST. There was a problem with the timeouts in the Amiga DNET, though. The timeouts are determined from the baudrate setting of the serial port. My port is set at 19200 baud so the timeouts become fairly short. Now, the Courier is an asymmetric modem: 9600 baud in one direction and 450 in the other. The 450 baud backchannel will cause the roundtrip time to be fairly long. If DNET calculates the timeouts from the 19200 figure, then it will timeout to early. I solved the problem by adding a switch to dnet, that supplies the baudrate to use in the timeout calculations. The default is to use the serial port setting, as before. 2000 baud seems to be a good value for the Courier. -- Johan Widen SICS, PO Box 1263, S-164 28 KISTA, SWEDEN Tel: +46 8 752 15 32 Ttx: 812 61 54 SICS S Fax: +46 8 751 72 30 Internet: jw@sics.se or {mcvax,munnari,ukc,unido}!enea!sics.se!jw
