[Default (upon shipment)]
All switches are set to Off (b=48).
[Description] • Changes the memory switch specified by a to the values specified with b.
• When (b = 48), turns the applicable bit off.
• When (b = 49), turns the applicable bit on.
• When (b = 50), does not change the applicable bit. Set (b = 50) as the reserved bit.
• Memory switch 2 (Msw 2: a = 2)
Msw Function Setting value
2-1 to 2-8 Reserved. 50
• Memory switch 8 (Msw 8: a = 8)
Msw Function Setting value
8-1 to 8-4 Reserved. 50

Releases Printer BUSY when the remaining capacity
of the receive buffer becomes 256 bytes.
48
Releases Printer BUSY when the remaining capacity
of the receive buffer becomes 138 bytes.
