is enough free space in flash PROM for the new file. The space required will be the size of the

program files to make up space (use command >delete filename).

a new session with the same radio.

3.3.4 Installing new firmware using the RS-232 serial port
On occasion, it may be necessary to install new firmware using the RS-232 port. This is generally a
less desirable method as the download time is much longer and you can only update the radio that is
directly connected to the PC, i.e., remote updates are not possible.
The serial upgrade uses a PC with a terminal emulator. Any emulator can be used, however, it must
have the facility to download a text file on demand. In the example below, the emulator used is
Windows HyperTerminal.
