I’am trying to setup a modem on a Mikrotik routerboard to do remote control over telcom line. Now i manage to setup the ppp and dialin functions the modem is initializing propperly and everything works, but if i switch off the router and switch it back on the router never loads the OS. There is a orange/red light next to the blue one that never goes off. If i switch the modem off and reboot the router the OS loads and then when i switch the modem on everything works fine but again i cant reboot the router once the modem is on.
This is fixed in .25, it happens when the console cable is unplugged (or may lose all signals in your case). The router doesn’t freeze, just the console. You can still log in with Winbox. Reboot will reset this console problem.
you have to set in BIOS that Setup can be entered with the key and not with ANY KEY. The modem received strange data over serial, sends some back, and routers enters setup. If you tell it to enter setup only by delete key then this will not happen. To do this:
<<<<<<<<<<<<<<<<
RouterBOOT booter 1.13
RouterBoard 112
CPU frequency: 175 MHz
Memory size: 16 MB
Press any key within 1 seconds to enter setup
RouterBOOT-1.13
What do you want to configure?
d - boot delay
k - boot key
s - serial console
o - boot device
u - cpu mode
r - reset configuration
e - format nand
g - upgrade firmware
i - board info
p - boot protocol
t - do memory testing
x - exit setup
your choice: k - boot key
Select key which will enter setup on boot:
1 - any key
2 - key only
your choice: 2 - key only
