kjt_serial_receive_header

Action:

Waits for a file header from serial port (Serial Link App format).

• IMPORTANT: This routine was changed in FLOS v561 - it no longer sets the load position, kjt_serial_receive_file now does that function.

Input Registers

• HL = Location of filename
• A = Time allowed in seconds before give up waiting

Output Registers :

• Zero Flag: If set, all OK
• IX = location of serial file header (details below)

If Zero Flag is NOT set, A = error code:

• $0f - checksum bad
• $11 - header reception error
• $14 - time out error
• $25 - filename mismatch

Notes: Filename can be * if any file is to be accepted.
