I released a new version of c2nload, the fastloader for my RS-232 based tape drive emulator (http://www.funet.fi/pub/cbm/crossplatform/tranfer/C2N232/). This version has two new features: the ability to disable automatic start-up of the program, and the ability to load data to the RAM area $d000-$dfff on the C64 and C128. It also fixes a bug on the 264 series: there, tape file names are 17 characters long, not 16. I measured the transfer speed on the C64, C128, Vic-20 and plus/4 (not on the PET, as my 8032 is a bit difficult to access). Loading a 3-byte program file takes almost 6 seconds. Loading a file from $400 to $ffff on the Commodore 64 takes 22.618 seconds real time (and virtually no user or system time), measured with two different files copied from /dev/random. The transfer of the last 64511 bytes takes 16.709 seconds, which yields a transfer rate of 3860.8 bytes per second. I would have expected that a 38,400 bps line with 8 data bits and one stop bit would only yield 3840 bytes per second. Marko Message was sent through the cbm-hackers mailing list
