Jiri, So that I can work out what the problem might be, please could you tell me what messages are appearing when you start the connection using the ROM driver with the bootstrap SD card inserted in the Ser-USB? I need to know this so that I can see whether the unit is functioning correctly at the most basic level.
If you get as far as the message confirming the Ser-USB Bootstrap Loader and the loading of the ROM extensions, then a DIR USB1_ command should bring up the directory of the boostrap partition. fyi You cannot mount a partition unless the drive or SD Card has been formatted first and you cannot mount a partition on a drive number that is already in use; so, if the boostrap worked, then a partition is already mounted as drive 1 so a MOUNT 1,1,1 will fail. ... But we can work through these issues once I am sure that the basic functions are working.

Using either ROM or disk driver, speed of 9600 or 19200, included SD card or another SD card, it activates the driver and communicates with SER-USB, but nothing more. Neither MOUNT 1,1,1 nor MOUNT 2,1,2 (as described on leaflet) works ("not found", "bad or changed medium" and sometimes "corrupted FAT" appears). I tried to initialise a new card using both FORMAT (physical device) and pm_exe. I have used 256 MB SD card (! I don't want to destroy the bootstrap partition on the included 1 GB SD card, so I did not experiment with it !). Format says, that it has -1 MB. And after formatting to 128 MB, 8 LBA per group, it says it was formatted to -32767 sectors. PM ("partition" command) says, that sector 0 is unreadable. "Initialise" command starts to checking disk and nothing more. I have tried both my SER-USB devices, and both behave the same way. I have tried both QDOS and SMSQ, no difference (excepting behavior of the pm_exe, as described in manual). I have tried the power cycle of SER-USB, taking card out and back in, but it is still the same. What I am doing wrong?
