IMSAI 8080esp boot.conf¶
The following information applies to Release v1.10.0 or later and is based on the documentation at https://thehighnibble.com/imsai8080/configure/.
The file /imsai/conf/boot.conf on the MicroSD card contains the boot
configuration in a simple "key=value" format.
Warning: there is no error checking! If the system does not start properly, you may have to check the file for typos.
Default configuration¶
The default configuration is as following:
### Network configuration
NTP_SERVER=pool.ntp.org

HOSTNAME=imsai8080
PORT=80
SSID=mySSID
PASSWORD=myPASSWORD
WIFI.sta.scan=1
#WIFI.password.hide=1
### UART configuration
#UART0=115200,cs8
#UART1=115200,cs8
### Performance parameters
#TTY.netsrv.buffer_delay=33
#LPT.netsrv.buffer_delay=33
### Harddisk image
HARDDISK=hd-ws4
### SIO-2 default port mappings (HAL)
#SIO1.portA.device=WEBTTY,UART0
#SIO1.portB.device=VIOKBD
#SIO2.portA.device=WEBPTR,UART1
#SIO2.portB.device=MODEM
### Modem initialization string. Example:
#MODEM.init=ATS0=1S15=1&A1 #S0=1 auto-answer after 1 ring, S15=1 enable telnet protocol
MODEM.init=ATS15=1 #S15=1 enable telnet protocol
Timezone settings¶
With TZ you define which timezone the device should use. This setting must
be a timezone in POSIX format like one of the following (based on
https://www.di-mgt.com.au/src/wclocktz.ini):

UART settings¶
The variables UART0 and UART1 configure the settings for the serial
ports. If no specific setting is configured, both UARTs will use
115200 bits/s with 8N1 (115200,cs8).
The following options can be combined using commas or spaces:
- Speed (bits/s):
110,300,1200,2400,4800,9600,19200,38400,57600,115200,230400 - Character size:
cs7- 7 bits,cs8- 8 bits - Stop bits:
cstopb- 2 stop bits, otherwise 1 - Parity: None, if no option is set,
parenb- even parity,parenb,parodd- odd parity
Examples:
- 9600 bit/s, 7 bits, 1 stop bit, no parity:
9600,cs7 - 19200 bit/s, 8 bits, 1 stop bit, even parity:
19200 cs8 parenb
