```
In this example, you can see the program counter is set to FF3F, which is the 6502 reset vector on the Acorn Atom.
## srec (sr)
Uploads srecords into memory
_Usage: sr_
There are no paramaters.
You should see a message:
Send file now..
Only the S1 srecord is currently understood, e.g.:
```
<S1><Count><Addr><Data>...<Data><CRC>
```
Here's a specific example:
```
S123A0004C10A0A94E8D0802A9A08D09024C33A0A9468D0402A9A08D0502A90F8D04B8A9A9
```
The command completes if no records are received within a short time period.
The linux utility srec_cat can be used to convert an arbitrary file into suitable srecords:
```
% srec_cat somefile -binary -offset 0x1900 -data_only > somefile.srec
```
This will turn a binary file (somefile) into srecord format (solefile.srec), with a loading address in memory of 0x1900.
## step (s)
Single steps one or more instructions.
