Why is Serial Port Speed on os4 Limited to 31250 in PREFS? Please help

HI guys the OS4 serial prefs only lets me select max speed of 31250? whats up with that? Even my classic amiga can go higher! Please help. Im using a sharp jx100 serial port flatbed scanner and need to up the speed. When i select serial in Prefs it only goes to 31250? Thanks

@magnetic

I don't the speed in serial prefs has anything to do with the speed that will be negotiated by the scannner, you should look in the scanner driver prgram for that.

Even at full speed (115Kb/s ?) the scanner will be slow.

@magnetic

The baudrate set in Serial prefs only applies when the SER: driver is used. Any other application using serial.device directly will set a baudrate on its own and hereby override the global prefs.

IMHO serial prefs is obsolete, should have been deleted ages ago. If you look at the devs:dosdrivers/SER file it should contain:

/* $VER: SER 52.1 (10.12.2006)
*
* SER: for A1 Amiga Hardware
*/

EHandler = L:Port-Handler
Priority = 5
StackSize = 2000
GlobVec = -1
Device = serial.device
Unit = 0
Flags = 0
Control = "8N1"
Baud = 115200

I suggest you delete envarc:sys/serial.prefs and move sys:prefs/serial to storage.

You can also move baud to the SER tooltype as BAUD=115200 so you can edit the icon instead of the file if you need to change it.

Thanks for the responses guys. I'm on a peg the device is pegserial.device. Can I just rename this to serial.device? (the native jx100 scanner software defaults to that I cant use the scanner with pegserial.device, I have to use the imagefx drivers)

don't rename it, use makelink so both names are available:

makelink devs:serial.device devs:pegserial.device

@Severin

THanks man never knew about that command! Ill try it when I get to the studio

@magnetic

There is also the Devs/NSDPatch.cfg file.

It has thorough instructions in a comment section at the top of the file, and at the bottom, there are several examples of device remapping for specific purposes on specific platforms.

It should be possible for you to create a remapping entry for your purpose.

Best regards,

Niels

You must be running some old amigaos version then? nowdays there's an universal serial.device for all NG platforms.

@smf

Just what I was going to say. The Final Edition version of serial.device says (when you do a "version full"):

serial.device 53.9 (14/06/2012)
Universal PPC version

@smf

I'm running os 4.1 update 6.

Then when you upgrade to Final Edition, all your serial device problems will be solved.

returns an error because I dont have a serial.device in devs!

@tonyw

version pegserial.device full

gives

ver 53.1 *(01/08/2009)


there is no serial.device present in devs:!

@magnetic

try:

makelink devs:serial.device devs:pegserial.device SOFT

In a shell type 'help makelink' for more info.
